Types of Research
Research is about using established methods to investigate a problem or question in detail with the aim of generating new knowledge about it.
It is a vital tool for scientific advancement because it allows researchers to prove or refute hypotheses based on clearly defined parameters, environments and assumptions. Due to this, it enables us to confidently contribute to knowledge as it allows research to be verified and replicated.
Knowing the types of research and what each of them focuses on will allow you to better plan your project, utilises the most appropriate methodologies and techniques and better communicate your findings to other researchers and supervisors.
Classification of Types of Research
There are various types of research that are classified according to their objective, depth of study, analysed data, time required to study the phenomenon and other factors. It’s important to note that a research project will not be limited to one type of research, but will likely use several.
According to its Purpose
Theoretical research.
Theoretical research, also referred to as pure or basic research, focuses on generating knowledge , regardless of its practical application. Here, data collection is used to generate new general concepts for a better understanding of a particular field or to answer a theoretical research question.
Results of this kind are usually oriented towards the formulation of theories and are usually based on documentary analysis, the development of mathematical formulas and the reflection of high-level researchers.
Applied Research
Here, the goal is to find strategies that can be used to address a specific research problem. Applied research draws on theory to generate practical scientific knowledge, and its use is very common in STEM fields such as engineering, computer science and medicine.
This type of research is subdivided into two types:
- Technological applied research : looks towards improving efficiency in a particular productive sector through the improvement of processes or machinery related to said productive processes.
- Scientific applied research : has predictive purposes. Through this type of research design, we can measure certain variables to predict behaviours useful to the goods and services sector, such as consumption patterns and viability of commercial projects.
![types of research project work Methodology Research](https://www.discoverphds.com/wp-content/uploads/2020/10/Methodology-Research.jpg)
According to your Depth of Scope
Exploratory research.
Exploratory research is used for the preliminary investigation of a subject that is not yet well understood or sufficiently researched. It serves to establish a frame of reference and a hypothesis from which an in-depth study can be developed that will enable conclusive results to be generated.
Because exploratory research is based on the study of little-studied phenomena, it relies less on theory and more on the collection of data to identify patterns that explain these phenomena.
Descriptive Research
The primary objective of descriptive research is to define the characteristics of a particular phenomenon without necessarily investigating the causes that produce it.
In this type of research, the researcher must take particular care not to intervene in the observed object or phenomenon, as its behaviour may change if an external factor is involved.
Explanatory Research
Explanatory research is the most common type of research method and is responsible for establishing cause-and-effect relationships that allow generalisations to be extended to similar realities. It is closely related to descriptive research, although it provides additional information about the observed object and its interactions with the environment.
Correlational Research
The purpose of this type of scientific research is to identify the relationship between two or more variables. A correlational study aims to determine whether a variable changes, how much the other elements of the observed system change.
According to the Type of Data Used
Qualitative research.
Qualitative methods are often used in the social sciences to collect, compare and interpret information, has a linguistic-semiotic basis and is used in techniques such as discourse analysis, interviews, surveys, records and participant observations.
In order to use statistical methods to validate their results, the observations collected must be evaluated numerically. Qualitative research, however, tends to be subjective, since not all data can be fully controlled. Therefore, this type of research design is better suited to extracting meaning from an event or phenomenon (the ‘why’) than its cause (the ‘how’).
Quantitative Research
Quantitative research study delves into a phenomena through quantitative data collection and using mathematical, statistical and computer-aided tools to measure them . This allows generalised conclusions to be projected over time.
![types of research project work Types of Research Methodology](https://www.discoverphds.com/wp-content/uploads/2020/10/Types-of-Research-Methodology.jpg)
According to the Degree of Manipulation of Variables
Experimental research.
It is about designing or replicating a phenomenon whose variables are manipulated under strictly controlled conditions in order to identify or discover its effect on another independent variable or object. The phenomenon to be studied is measured through study and control groups, and according to the guidelines of the scientific method.
Non-Experimental Research
Also known as an observational study, it focuses on the analysis of a phenomenon in its natural context. As such, the researcher does not intervene directly, but limits their involvement to measuring the variables required for the study. Due to its observational nature, it is often used in descriptive research.
Quasi-Experimental Research
It controls only some variables of the phenomenon under investigation and is therefore not entirely experimental. In this case, the study and the focus group cannot be randomly selected, but are chosen from existing groups or populations . This is to ensure the collected data is relevant and that the knowledge, perspectives and opinions of the population can be incorporated into the study.
According to the Type of Inference
Deductive investigation.
In this type of research, reality is explained by general laws that point to certain conclusions; conclusions are expected to be part of the premise of the research problem and considered correct if the premise is valid and the inductive method is applied correctly.
Inductive Research
In this type of research, knowledge is generated from an observation to achieve a generalisation. It is based on the collection of specific data to develop new theories.
Hypothetical-Deductive Investigation
It is based on observing reality to make a hypothesis, then use deduction to obtain a conclusion and finally verify or reject it through experience.
![types of research project work Descriptive Research Design](https://www.discoverphds.com/wp-content/uploads/2020/10/Descriptive-Research-Design.jpg)
According to the Time in Which it is Carried Out
Longitudinal study (also referred to as diachronic research).
It is the monitoring of the same event, individual or group over a defined period of time. It aims to track changes in a number of variables and see how they evolve over time. It is often used in medical, psychological and social areas .
Cross-Sectional Study (also referred to as Synchronous Research)
Cross-sectional research design is used to observe phenomena, an individual or a group of research subjects at a given time.
According to The Sources of Information
Primary research.
This fundamental research type is defined by the fact that the data is collected directly from the source, that is, it consists of primary, first-hand information.
Secondary research
Unlike primary research, secondary research is developed with information from secondary sources, which are generally based on scientific literature and other documents compiled by another researcher.
![types of research project work Action Research Methods](https://www.discoverphds.com/wp-content/uploads/2020/10/Action-Research-Methods.jpg)
According to How the Data is Obtained
Documentary (cabinet).
Documentary research, or secondary sources, is based on a systematic review of existing sources of information on a particular subject. This type of scientific research is commonly used when undertaking literature reviews or producing a case study.
Field research study involves the direct collection of information at the location where the observed phenomenon occurs.
From Laboratory
Laboratory research is carried out in a controlled environment in order to isolate a dependent variable and establish its relationship with other variables through scientific methods.
Mixed-Method: Documentary, Field and/or Laboratory
Mixed research methodologies combine results from both secondary (documentary) sources and primary sources through field or laboratory research.

What is Research? Definition, Types, Methods, and Examples
Academic research is a methodical way of exploring new ideas or understanding things we already know. It involves gathering and studying information to answer questions or test ideas and requires careful thinking and persistence to reach meaningful conclusions. Let’s try to understand what research is.
Table of Contents
Why is research important?
Whether it’s doing experiments, analyzing data, or studying old documents, research helps us learn more about the world. Without it, we rely on guesswork and hearsay, often leading to mistakes and misconceptions. By using systematic methods, research helps us see things clearly, free from biases. (1)
What is the purpose of research?
In the real world, academic research is also a key driver of innovation. It brings many benefits, such as creating valuable opportunities and fostering partnerships between academia and industry. By turning research into products and services, science makes meaningful improvements to people’s lives and boosts the economy. (2)(3)
What are the characteristics of research?
The research process collects accurate information systematically. Logic is used to analyze the collected data and find insights. Checking the collected data thoroughly ensures accuracy. Research also leads to new questions using existing data.
Accuracy is key in research, which requires precise data collection and analysis. In scientific research, laboratories ensure accuracy by carefully calibrating instruments and controlling experiments. Every step is checked to maintain integrity, from instruments to final results. Accuracy gives reliable insights, which in turn help advance knowledge.
Types of research
The different forms of research serve distinct purposes in expanding knowledge and understanding:
- Exploratory research ventures into uncharted territories, exploring new questions or problem areas without aiming for conclusive answers. For instance, a study may delve into unexplored market segments to better understand consumer behaviour patterns.
- Descriptive research delves into current issues by collecting and analyzing data to describe the behaviour of a sample population. For instance, a survey may investigate millennials’ spending habits to gain insights into their purchasing behaviours.
- Explanatory research, also known as causal research, seeks to understand the impact of specific changes in existing procedures. An example might be a study examining how changes in drug dosage over some time improve patients’ health.
- Correlational research examines connections between two sets of data to uncover meaningful relationships. For instance, a study may analyze the relationship between advertising spending and sales revenue.
- Theoretical research deepens existing knowledge without attempting to solve specific problems. For example, a study may explore theoretical frameworks to understand the underlying principles of human behaviour.
- Applied research focuses on real-world issues and aims to provide practical solutions. An example could be a study investigating the effectiveness of a new teaching method in improving student performance in schools. (4)
Types of research methods
- Qualitative Method: Qualitative research gathers non-numerical data through interactions with participants. Methods include one-to-one interviews, focus groups, ethnographic studies, text analysis, and case studies. For example, a researcher interviews cancer patients to understand how different treatments impact their lives emotionally.
- Quantitative Method: Quantitative methods deal with numbers and measurable data to understand relationships between variables. They use systematic methods to investigate events and aim to explain or predict outcomes. For example, Researchers study how exercise affects heart health by measuring variables like heart rate and blood pressure in a large group before and after an exercise program. (5)
Basic steps involved in the research process
Here are the basic steps to help you understand the research process:
- Choose your topic: Decide the specific subject or area that you want to study and investigate. This decision is the foundation of your research journey.
- Find information: Look for information related to your research topic. You can search in journals, books, online, or ask experts for help.
- Assess your sources: Make sure the information you find is reliable and trustworthy. Check the author’s credentials and the publication date.
- Take notes: Write down important information from your sources that you can use in your research.
- Write your paper: Use your notes to write your research paper. Broadly, start with an introduction, then write the body of your paper, and finish with a conclusion.
- Cite your sources: Give credit to the sources you used by including citations in your paper.
- Proofread: Check your paper thoroughly for any errors in spelling, grammar, or punctuation before you submit it. (6)
How to ensure research accuracy?
Ensuring accuracy in research is a mix of several essential steps:
- Clarify goals: Start by defining clear objectives for your research. Identify your research question, hypothesis, and variables of interest. This clarity will help guide your data collection and analysis methods, ensuring that your research stays focused and purposeful.
- Use reliable data: Select trustworthy sources for your information, whether they are primary data collected by you or secondary data obtained from other sources. For example, if you’re studying climate change, use data from reputable scientific organizations with transparent methodologies.
- Validate data: Validate your data to ensure it meets the standards of your research project. Check for errors, outliers, and inconsistencies at different stages, such as during data collection, entry, cleaning, or analysis.
- Document processes: Documenting your data collection and analysis processes is essential for transparency and reproducibility. Record details such as data collection methods, cleaning procedures, and analysis techniques used. This documentation not only helps you keep track of your research but also enables others to understand and replicate your work.
- Review results: Finally, review and verify your research findings to confirm their accuracy and reliability. Double-check your analyses, cross-reference your data, and seek feedback from peers or supervisors. (7)
Research is crucial for better understanding our world and for social and economic growth. By following ethical guidelines and ensuring accuracy, researchers play a critical role in driving this progress, whether through exploring new topics or deepening existing knowledge.

When embarking on a research project, selecting the right methodology can be the difference between success and failure. With various methods available, each suited to different types of research, it’s essential you make an informed choice. This blog post will provide tips on how to choose a research methodology that best fits your research goals .
We’ll start with definitions: Research is the systematic process of exploring, investigating, and discovering new information or validating existing knowledge. It involves defining questions, collecting data, analyzing results, and drawing conclusions.
Meanwhile, a research methodology is a structured plan that outlines how your research is to be conducted. A complete methodology should detail the strategies, processes, and techniques you plan to use for your data collection and analysis.
![types of research project work a computer keyboard being worked by a researcher](https://www.uopeople.edu/wp-content/uploads/2024/06/Comprehensive-guide-to-types-of-research_1.webp)
Research Methods
The first step of a research methodology is to identify a focused research topic, which is the question you seek to answer. By setting clear boundaries on the scope of your research, you can concentrate on specific aspects of a problem without being overwhelmed by information. This will produce more accurate findings.
Along with clarifying your research topic, your methodology should also address your research methods. Let’s look at the four main types of research: descriptive, correlational, experimental, and diagnostic.
Descriptive Research
Descriptive research is an approach designed to describe the characteristics of a population systematically and accurately. This method focuses on answering “what” questions by providing detailed observations about the subject. Descriptive research employs surveys, observational studies , and case studies to gather qualitative or quantitative data.
A real-world example of descriptive research is a survey investigating consumer behavior toward a competitor’s product. By analyzing the survey results, the company can gather detailed insights into how consumers perceive a competitor’s product, which can inform their marketing strategies and product development.
Correlational Research
Correlational research examines the statistical relationship between two or more variables to determine whether a relationship exists. Correlational research is particularly useful when ethical or practical constraints prevent experimental manipulation. It is often employed in fields such as psychology, education, and health sciences to provide insights into complex real-world interactions, helping to develop theories and inform further experimental research.
An example of correlational research is the study of the relationship between smoking and lung cancer. Researchers observe and collect data on individuals’ smoking habits and the incidence of lung cancer to determine if there is a correlation between the two variables. This type of research helps identify patterns and relationships, indicating whether increased smoking is associated with higher rates of lung cancer.
Experimental Research
Experimental research is a scientific approach where researchers manipulate one or more independent variables to observe their effect on a dependent variable. This method is designed to establish cause-and-effect relationships. Fields like psychology , medicine, and social sciences frequently employ experimental research to test hypotheses and theories under controlled conditions.
A real-world example of experimental research is Pavlov’s Dog experiment. In this experiment, Ivan Pavlov demonstrated classical conditioning by ringing a bell each time he fed his dogs. After repeating this process multiple times, the dogs began to salivate just by hearing the bell, even when no food was presented. This experiment helped to illustrate how certain stimuli can elicit specific responses through associative learning.
Diagnostic Research
Diagnostic research tries to accurately diagnose a problem by identifying its underlying causes. This type of research is crucial for understanding complex situations where a precise diagnosis is necessary for formulating effective solutions. It involves methods such as case studies and data analysis and often integrates both qualitative and quantitative data to provide a comprehensive view of the issue at hand.
An example of diagnostic research is studying the causes of a specific illness outbreak. During an outbreak of a respiratory virus, researchers might conduct diagnostic research to determine the factors contributing to the spread of the virus. This could involve analyzing patient data, testing environmental samples, and evaluating potential sources of infection. The goal is to identify the root causes and contributing factors to develop effective containment and prevention strategies.
Using an established research method is imperative, no matter if you are researching for marketing , technology , healthcare , engineering, or social science. A methodology lends legitimacy to your research by ensuring your data is both consistent and credible. A well-defined methodology also enhances the reliability and validity of the research findings, which is crucial for drawing accurate and meaningful conclusions.
Additionally, methodologies help researchers stay focused and on track, limiting the scope of the study to relevant questions and objectives. This not only improves the quality of the research but also ensures that the study can be replicated and verified by other researchers, further solidifying its scientific value.
![types of research project work a graphical depiction of the wide possibilities of research](https://www.uopeople.edu/wp-content/uploads/2024/06/Comprehensive-guide-to-types-of-research_2.webp)
How to Choose a Research Methodology
Choosing the best research methodology for your project involves several key steps to ensure that your approach aligns with your research goals and questions. Here’s a simplified guide to help you make the best choice.
Understand Your Goals
Clearly define the objectives of your research. What do you aim to discover, prove, or understand? Understanding your goals helps in selecting a methodology that aligns with your research purpose.
Consider the Nature of Your Data
Determine whether your research will involve numerical data, textual data, or both. Quantitative methods are best for numerical data, while qualitative methods are suitable for textual or thematic data.
Understand the Purpose of Each Methodology
Becoming familiar with the four types of research – descriptive, correlational, experimental, and diagnostic – will enable you to select the most appropriate method for your research. Many times, you will want to use a combination of methods to gather meaningful data.
Evaluate Resources and Constraints
Consider the resources available to you, including time, budget, and access to data. Some methodologies may require more resources or longer timeframes to implement effectively.
Review Similar Studies
Look at previous research in your field to see which methodologies were successful. This can provide insights and help you choose a proven approach.
By following these steps, you can select a research methodology that best fits your project’s requirements and ensures robust, credible results.
Completing Your Research Project
Upon completing your research, the next critical step is to analyze and interpret the data you’ve collected. This involves summarizing the key findings, identifying patterns, and determining how these results address your initial research questions. By thoroughly examining the data, you can draw meaningful conclusions that contribute to the body of knowledge in your field.
It’s essential that you present these findings clearly and concisely, using charts, graphs, and tables to enhance comprehension. Furthermore, discuss the implications of your results, any limitations encountered during the study, and how your findings align with or challenge existing theories.
Your research project should conclude with a strong statement that encapsulates the essence of your research and its broader impact. This final section should leave readers with a clear understanding of the value of your work and inspire continued exploration and discussion in the field.
Now that you know how to perform quality research , it’s time to get started! Applying the right research methodologies can make a significant difference in the accuracy and reliability of your findings. Remember, the key to successful research is not just in collecting data, but in analyzing it thoughtfully and systematically to draw meaningful conclusions. So, dive in, explore, and contribute to the ever-growing body of knowledge with confidence. Happy researching!

Introduction
Before beginning your paper, you need to decide how you plan to design the study .
The research design refers to the overall strategy and analytical approach that you have chosen in order to integrate, in a coherent and logical way, the different components of the study, thus ensuring that the research problem will be thoroughly investigated. It constitutes the blueprint for the collection, measurement, and interpretation of information and data. Note that the research problem determines the type of design you choose, not the other way around!
De Vaus, D. A. Research Design in Social Research . London: SAGE, 2001; Trochim, William M.K. Research Methods Knowledge Base. 2006.
General Structure and Writing Style
The function of a research design is to ensure that the evidence obtained enables you to effectively address the research problem logically and as unambiguously as possible . In social sciences research, obtaining information relevant to the research problem generally entails specifying the type of evidence needed to test the underlying assumptions of a theory, to evaluate a program, or to accurately describe and assess meaning related to an observable phenomenon.
With this in mind, a common mistake made by researchers is that they begin their investigations before they have thought critically about what information is required to address the research problem. Without attending to these design issues beforehand, the overall research problem will not be adequately addressed and any conclusions drawn will run the risk of being weak and unconvincing. As a consequence, the overall validity of the study will be undermined.
The length and complexity of describing the research design in your paper can vary considerably, but any well-developed description will achieve the following :
- Identify the research problem clearly and justify its selection, particularly in relation to any valid alternative designs that could have been used,
- Review and synthesize previously published literature associated with the research problem,
- Clearly and explicitly specify hypotheses [i.e., research questions] central to the problem,
- Effectively describe the information and/or data which will be necessary for an adequate testing of the hypotheses and explain how such information and/or data will be obtained, and
- Describe the methods of analysis to be applied to the data in determining whether or not the hypotheses are true or false.
The research design is usually incorporated into the introduction of your paper . You can obtain an overall sense of what to do by reviewing studies that have utilized the same research design [e.g., using a case study approach]. This can help you develop an outline to follow for your own paper.
NOTE: Use the SAGE Research Methods Online and Cases and the SAGE Research Methods Videos databases to search for scholarly resources on how to apply specific research designs and methods . The Research Methods Online database contains links to more than 175,000 pages of SAGE publisher's book, journal, and reference content on quantitative, qualitative, and mixed research methodologies. Also included is a collection of case studies of social research projects that can be used to help you better understand abstract or complex methodological concepts. The Research Methods Videos database contains hours of tutorials, interviews, video case studies, and mini-documentaries covering the entire research process.

Action Research Design
Definition and Purpose
The essentials of action research design follow a characteristic cycle whereby initially an exploratory stance is adopted, where an understanding of a problem is developed and plans are made for some form of interventionary strategy. Then the intervention is carried out [the "action" in action research] during which time, pertinent observations are collected in various forms. The new interventional strategies are carried out, and this cyclic process repeats, continuing until a sufficient understanding of [or a valid implementation solution for] the problem is achieved. The protocol is iterative or cyclical in nature and is intended to foster deeper understanding of a given situation, starting with conceptualizing and particularizing the problem and moving through several interventions and evaluations.
What do these studies tell you ?
- This is a collaborative and adaptive research design that lends itself to use in work or community situations.
- Design focuses on pragmatic and solution-driven research outcomes rather than testing theories.
- When practitioners use action research, it has the potential to increase the amount they learn consciously from their experience; the action research cycle can be regarded as a learning cycle.
- Action research studies often have direct and obvious relevance to improving practice and advocating for change.
- There are no hidden controls or preemption of direction by the researcher.
What these studies don't tell you ?
- It is harder to do than conducting conventional research because the researcher takes on responsibilities of advocating for change as well as for researching the topic.
- Action research is much harder to write up because it is less likely that you can use a standard format to report your findings effectively [i.e., data is often in the form of stories or observation].
- Personal over-involvement of the researcher may bias research results.
- The cyclic nature of action research to achieve its twin outcomes of action [e.g. change] and research [e.g. understanding] is time-consuming and complex to conduct.
- Advocating for change usually requires buy-in from study participants.

Case Study Design
A case study is an in-depth study of a particular research problem rather than a sweeping statistical survey or comprehensive comparative inquiry. It is often used to narrow down a very broad field of research into one or a few easily researchable examples. The case study research design is also useful for testing whether a specific theory and model actually applies to phenomena in the real world. It is a useful design when not much is known about an issue or phenomenon.
- Approach excels at bringing us to an understanding of a complex issue through detailed contextual analysis of a limited number of events or conditions and their relationships.
- A researcher using a case study design can apply a variety of methodologies and rely on a variety of sources to investigate a research problem.
- Design can extend experience or add strength to what is already known through previous research.
- Social scientists, in particular, make wide use of this research design to examine contemporary real-life situations and provide the basis for the application of concepts and theories and the extension of methodologies.
- The design can provide detailed descriptions of specific and rare cases.
- A single or small number of cases offers little basis for establishing reliability or to generalize the findings to a wider population of people, places, or things.
- Intense exposure to the study of a case may bias a researcher's interpretation of the findings.
- Design does not facilitate assessment of cause and effect relationships.
- Vital information may be missing, making the case hard to interpret.
- The case may not be representative or typical of the larger problem being investigated.
- If the criteria for selecting a case is because it represents a very unusual or unique phenomenon or problem for study, then your interpretation of the findings can only apply to that particular case.

Causal Design
Causality studies may be thought of as understanding a phenomenon in terms of conditional statements in the form, “If X, then Y.” This type of research is used to measure what impact a specific change will have on existing norms and assumptions. Most social scientists seek causal explanations that reflect tests of hypotheses. Causal effect (nomothetic perspective) occurs when variation in one phenomenon, an independent variable, leads to or results, on average, in variation in another phenomenon, the dependent variable.
Conditions necessary for determining causality:
- Empirical association -- a valid conclusion is based on finding an association between the independent variable and the dependent variable.
- Appropriate time order -- to conclude that causation was involved, one must see that cases were exposed to variation in the independent variable before variation in the dependent variable.
- Nonspuriousness -- a relationship between two variables that is not due to variation in a third variable.
- Causality research designs assist researchers in understanding why the world works the way it does through the process of proving a causal link between variables and by the process of eliminating other possibilities.
- Replication is possible.
- There is greater confidence the study has internal validity due to the systematic subject selection and equity of groups being compared.
- Not all relationships are causal! The possibility always exists that, by sheer coincidence, two unrelated events appear to be related [e.g., Punxatawney Phil could accurately predict the duration of Winter for five consecutive years but, the fact remains, he's just a big, furry rodent].
- Conclusions about causal relationships are difficult to determine due to a variety of extraneous and confounding variables that exist in a social environment. This means causality can only be inferred, never proven.
- If two variables are correlated, the cause must come before the effect. However, even though two variables might be causally related, it can sometimes be difficult to determine which variable comes first and, therefore, to establish which variable is the actual cause and which is the actual effect.

Cohort Design
Often used in the medical sciences, but also found in the applied social sciences, a cohort study generally refers to a study conducted over a period of time involving members of a population which the subject or representative member comes from, and who are united by some commonality or similarity. Using a quantitative framework, a cohort study makes note of statistical occurrence within a specialized subgroup, united by same or similar characteristics that are relevant to the research problem being investigated, rather than studying statistical occurrence within the general population. Using a qualitative framework, cohort studies generally gather data using methods of observation. Cohorts can be either "open" or "closed."
- Open Cohort Studies [dynamic populations, such as the population of Los Angeles] involve a population that is defined just by the state of being a part of the study in question (and being monitored for the outcome). Date of entry and exit from the study is individually defined, therefore, the size of the study population is not constant. In open cohort studies, researchers can only calculate rate based data, such as, incidence rates and variants thereof.
- Closed Cohort Studies [static populations, such as patients entered into a clinical trial] involve participants who enter into the study at one defining point in time and where it is presumed that no new participants can enter the cohort. Given this, the number of study participants remains constant (or can only decrease).
- The use of cohorts is often mandatory because a randomized control study may be unethical. For example, you cannot deliberately expose people to asbestos, you can only study its effects on those who have already been exposed. Research that measures risk factors often relies upon cohort designs.
- Because cohort studies measure potential causes before the outcome has occurred, they can demonstrate that these “causes” preceded the outcome, thereby avoiding the debate as to which is the cause and which is the effect.
- Cohort analysis is highly flexible and can provide insight into effects over time and related to a variety of different types of changes [e.g., social, cultural, political, economic, etc.].
- Either original data or secondary data can be used in this design.
- In cases where a comparative analysis of two cohorts is made [e.g., studying the effects of one group exposed to asbestos and one that has not], a researcher cannot control for all other factors that might differ between the two groups. These factors are known as confounding variables.
- Cohort studies can end up taking a long time to complete if the researcher must wait for the conditions of interest to develop within the group. This also increases the chance that key variables change during the course of the study, potentially impacting the validity of the findings.
- Due to the lack of randominization in the cohort design, its external validity is lower than that of study designs where the researcher randomly assigns participants.

Cross-Sectional Design
Cross-sectional research designs have three distinctive features: no time dimension; a reliance on existing differences rather than change following intervention; and, groups are selected based on existing differences rather than random allocation. The cross-sectional design can only measure differences between or from among a variety of people, subjects, or phenomena rather than a process of change. As such, researchers using this design can only employ a relatively passive approach to making causal inferences based on findings.
- Cross-sectional studies provide a clear 'snapshot' of the outcome and the characteristics associated with it, at a specific point in time.
- Unlike an experimental design, where there is an active intervention by the researcher to produce and measure change or to create differences, cross-sectional designs focus on studying and drawing inferences from existing differences between people, subjects, or phenomena.
- Entails collecting data at and concerning one point in time. While longitudinal studies involve taking multiple measures over an extended period of time, cross-sectional research is focused on finding relationships between variables at one moment in time.
- Groups identified for study are purposely selected based upon existing differences in the sample rather than seeking random sampling.
- Cross-section studies are capable of using data from a large number of subjects and, unlike observational studies, is not geographically bound.
- Can estimate prevalence of an outcome of interest because the sample is usually taken from the whole population.
- Because cross-sectional designs generally use survey techniques to gather data, they are relatively inexpensive and take up little time to conduct.
- Finding people, subjects, or phenomena to study that are very similar except in one specific variable can be difficult.
- Results are static and time bound and, therefore, give no indication of a sequence of events or reveal historical or temporal contexts.
- Studies cannot be utilized to establish cause and effect relationships.
- This design only provides a snapshot of analysis so there is always the possibility that a study could have differing results if another time-frame had been chosen.
- There is no follow up to the findings.

Descriptive Design
Descriptive research designs help provide answers to the questions of who, what, when, where, and how associated with a particular research problem; a descriptive study cannot conclusively ascertain answers to why. Descriptive research is used to obtain information concerning the current status of the phenomena and to describe "what exists" with respect to variables or conditions in a situation.
- The subject is being observed in a completely natural and unchanged natural environment. True experiments, whilst giving analyzable data, often adversely influence the normal behavior of the subject [a.k.a., the Heisenberg effect whereby measurements of certain systems cannot be made without affecting the systems].
- Descriptive research is often used as a pre-cursor to more quantitative research designs with the general overview giving some valuable pointers as to what variables are worth testing quantitatively.
- If the limitations are understood, they can be a useful tool in developing a more focused study.
- Descriptive studies can yield rich data that lead to important recommendations in practice.
- Appoach collects a large amount of data for detailed analysis.
- The results from a descriptive research cannot be used to discover a definitive answer or to disprove a hypothesis.
- Because descriptive designs often utilize observational methods [as opposed to quantitative methods], the results cannot be replicated.
- The descriptive function of research is heavily dependent on instrumentation for measurement and observation.

Experimental Design
A blueprint of the procedure that enables the researcher to maintain control over all factors that may affect the result of an experiment. In doing this, the researcher attempts to determine or predict what may occur. Experimental research is often used where there is time priority in a causal relationship (cause precedes effect), there is consistency in a causal relationship (a cause will always lead to the same effect), and the magnitude of the correlation is great. The classic experimental design specifies an experimental group and a control group. The independent variable is administered to the experimental group and not to the control group, and both groups are measured on the same dependent variable. Subsequent experimental designs have used more groups and more measurements over longer periods. True experiments must have control, randomization, and manipulation.
- Experimental research allows the researcher to control the situation. In so doing, it allows researchers to answer the question, “What causes something to occur?”
- Permits the researcher to identify cause and effect relationships between variables and to distinguish placebo effects from treatment effects.
- Experimental research designs support the ability to limit alternative explanations and to infer direct causal relationships in the study.
- Approach provides the highest level of evidence for single studies.
- The design is artificial, and results may not generalize well to the real world.
- The artificial settings of experiments may alter the behaviors or responses of participants.
- Experimental designs can be costly if special equipment or facilities are needed.
- Some research problems cannot be studied using an experiment because of ethical or technical reasons.
- Difficult to apply ethnographic and other qualitative methods to experimentally designed studies.

Exploratory Design
An exploratory design is conducted about a research problem when there are few or no earlier studies to refer to or rely upon to predict an outcome . The focus is on gaining insights and familiarity for later investigation or undertaken when research problems are in a preliminary stage of investigation. Exploratory designs are often used to establish an understanding of how best to proceed in studying an issue or what methodology would effectively apply to gathering information about the issue.
The goals of exploratory research are intended to produce the following possible insights:
- Familiarity with basic details, settings, and concerns.
- Well grounded picture of the situation being developed.
- Generation of new ideas and assumptions.
- Development of tentative theories or hypotheses.
- Determination about whether a study is feasible in the future.
- Issues get refined for more systematic investigation and formulation of new research questions.
- Direction for future research and techniques get developed.
- Design is a useful approach for gaining background information on a particular topic.
- Exploratory research is flexible and can address research questions of all types (what, why, how).
- Provides an opportunity to define new terms and clarify existing concepts.
- Exploratory research is often used to generate formal hypotheses and develop more precise research problems.
- In the policy arena or applied to practice, exploratory studies help establish research priorities and where resources should be allocated.
- Exploratory research generally utilizes small sample sizes and, thus, findings are typically not generalizable to the population at large.
- The exploratory nature of the research inhibits an ability to make definitive conclusions about the findings. They provide insight but not definitive conclusions.
- The research process underpinning exploratory studies is flexible but often unstructured, leading to only tentative results that have limited value to decision-makers.
- Design lacks rigorous standards applied to methods of data gathering and analysis because one of the areas for exploration could be to determine what method or methodologies could best fit the research problem.

Field Research Design
Sometimes referred to as ethnography or participant observation, designs around field research encompass a variety of interpretative procedures [e.g., observation and interviews] rooted in qualitative approaches to studying people individually or in groups while inhabiting their natural environment as opposed to using survey instruments or other forms of impersonal methods of data gathering. Information acquired from observational research takes the form of “ field notes ” that involves documenting what the researcher actually sees and hears while in the field. Findings do not consist of conclusive statements derived from numbers and statistics because field research involves analysis of words and observations of behavior. Conclusions, therefore, are developed from an interpretation of findings that reveal overriding themes, concepts, and ideas. More information can be found HERE .
- Field research is often necessary to fill gaps in understanding the research problem applied to local conditions or to specific groups of people that cannot be ascertained from existing data.
- The research helps contextualize already known information about a research problem, thereby facilitating ways to assess the origins, scope, and scale of a problem and to gage the causes, consequences, and means to resolve an issue based on deliberate interaction with people in their natural inhabited spaces.
- Enables the researcher to corroborate or confirm data by gathering additional information that supports or refutes findings reported in prior studies of the topic.
- Because the researcher in embedded in the field, they are better able to make observations or ask questions that reflect the specific cultural context of the setting being investigated.
- Observing the local reality offers the opportunity to gain new perspectives or obtain unique data that challenges existing theoretical propositions or long-standing assumptions found in the literature.
What these studies don't tell you
- A field research study requires extensive time and resources to carry out the multiple steps involved with preparing for the gathering of information, including for example, examining background information about the study site, obtaining permission to access the study site, and building trust and rapport with subjects.
- Requires a commitment to staying engaged in the field to ensure that you can adequately document events and behaviors as they unfold.
- The unpredictable nature of fieldwork means that researchers can never fully control the process of data gathering. They must maintain a flexible approach to studying the setting because events and circumstances can change quickly or unexpectedly.
- Findings can be difficult to interpret and verify without access to documents and other source materials that help to enhance the credibility of information obtained from the field [i.e., the act of triangulating the data].
- Linking the research problem to the selection of study participants inhabiting their natural environment is critical. However, this specificity limits the ability to generalize findings to different situations or in other contexts or to infer courses of action applied to other settings or groups of people.
- The reporting of findings must take into account how the researcher themselves may have inadvertently affected respondents and their behaviors.
Historical Design
The purpose of a historical research design is to collect, verify, and synthesize evidence from the past to establish facts that defend or refute a hypothesis. It uses secondary sources and a variety of primary documentary evidence, such as, diaries, official records, reports, archives, and non-textual information [maps, pictures, audio and visual recordings]. The limitation is that the sources must be both authentic and valid.
- The historical research design is unobtrusive; the act of research does not affect the results of the study.
- The historical approach is well suited for trend analysis.
- Historical records can add important contextual background required to more fully understand and interpret a research problem.
- There is often no possibility of researcher-subject interaction that could affect the findings.
- Historical sources can be used over and over to study different research problems or to replicate a previous study.
- The ability to fulfill the aims of your research are directly related to the amount and quality of documentation available to understand the research problem.
- Since historical research relies on data from the past, there is no way to manipulate it to control for contemporary contexts.
- Interpreting historical sources can be very time consuming.
- The sources of historical materials must be archived consistently to ensure access. This may especially challenging for digital or online-only sources.
- Original authors bring their own perspectives and biases to the interpretation of past events and these biases are more difficult to ascertain in historical resources.
- Due to the lack of control over external variables, historical research is very weak with regard to the demands of internal validity.
- It is rare that the entirety of historical documentation needed to fully address a research problem is available for interpretation, therefore, gaps need to be acknowledged.

Longitudinal Design
A longitudinal study follows the same sample over time and makes repeated observations. For example, with longitudinal surveys, the same group of people is interviewed at regular intervals, enabling researchers to track changes over time and to relate them to variables that might explain why the changes occur. Longitudinal research designs describe patterns of change and help establish the direction and magnitude of causal relationships. Measurements are taken on each variable over two or more distinct time periods. This allows the researcher to measure change in variables over time. It is a type of observational study sometimes referred to as a panel study.
- Longitudinal data facilitate the analysis of the duration of a particular phenomenon.
- Enables survey researchers to get close to the kinds of causal explanations usually attainable only with experiments.
- The design permits the measurement of differences or change in a variable from one period to another [i.e., the description of patterns of change over time].
- Longitudinal studies facilitate the prediction of future outcomes based upon earlier factors.
- The data collection method may change over time.
- Maintaining the integrity of the original sample can be difficult over an extended period of time.
- It can be difficult to show more than one variable at a time.
- This design often needs qualitative research data to explain fluctuations in the results.
- A longitudinal research design assumes present trends will continue unchanged.
- It can take a long period of time to gather results.
- There is a need to have a large sample size and accurate sampling to reach representativness.

Meta-Analysis Design
Meta-analysis is an analytical methodology designed to systematically evaluate and summarize the results from a number of individual studies, thereby, increasing the overall sample size and the ability of the researcher to study effects of interest. The purpose is to not simply summarize existing knowledge, but to develop a new understanding of a research problem using synoptic reasoning. The main objectives of meta-analysis include analyzing differences in the results among studies and increasing the precision by which effects are estimated. A well-designed meta-analysis depends upon strict adherence to the criteria used for selecting studies and the availability of information in each study to properly analyze their findings. Lack of information can severely limit the type of analyzes and conclusions that can be reached. In addition, the more dissimilarity there is in the results among individual studies [heterogeneity], the more difficult it is to justify interpretations that govern a valid synopsis of results. A meta-analysis needs to fulfill the following requirements to ensure the validity of your findings:
- Clearly defined description of objectives, including precise definitions of the variables and outcomes that are being evaluated;
- A well-reasoned and well-documented justification for identification and selection of the studies;
- Assessment and explicit acknowledgment of any researcher bias in the identification and selection of those studies;
- Description and evaluation of the degree of heterogeneity among the sample size of studies reviewed; and,
- Justification of the techniques used to evaluate the studies.
- Can be an effective strategy for determining gaps in the literature.
- Provides a means of reviewing research published about a particular topic over an extended period of time and from a variety of sources.
- Is useful in clarifying what policy or programmatic actions can be justified on the basis of analyzing research results from multiple studies.
- Provides a method for overcoming small sample sizes in individual studies that previously may have had little relationship to each other.
- Can be used to generate new hypotheses or highlight research problems for future studies.
- Small violations in defining the criteria used for content analysis can lead to difficult to interpret and/or meaningless findings.
- A large sample size can yield reliable, but not necessarily valid, results.
- A lack of uniformity regarding, for example, the type of literature reviewed, how methods are applied, and how findings are measured within the sample of studies you are analyzing, can make the process of synthesis difficult to perform.
- Depending on the sample size, the process of reviewing and synthesizing multiple studies can be very time consuming.

Mixed-Method Design
- Narrative and non-textual information can add meaning to numeric data, while numeric data can add precision to narrative and non-textual information.
- Can utilize existing data while at the same time generating and testing a grounded theory approach to describe and explain the phenomenon under study.
- A broader, more complex research problem can be investigated because the researcher is not constrained by using only one method.
- The strengths of one method can be used to overcome the inherent weaknesses of another method.
- Can provide stronger, more robust evidence to support a conclusion or set of recommendations.
- May generate new knowledge new insights or uncover hidden insights, patterns, or relationships that a single methodological approach might not reveal.
- Produces more complete knowledge and understanding of the research problem that can be used to increase the generalizability of findings applied to theory or practice.
- A researcher must be proficient in understanding how to apply multiple methods to investigating a research problem as well as be proficient in optimizing how to design a study that coherently melds them together.
- Can increase the likelihood of conflicting results or ambiguous findings that inhibit drawing a valid conclusion or setting forth a recommended course of action [e.g., sample interview responses do not support existing statistical data].
- Because the research design can be very complex, reporting the findings requires a well-organized narrative, clear writing style, and precise word choice.
- Design invites collaboration among experts. However, merging different investigative approaches and writing styles requires more attention to the overall research process than studies conducted using only one methodological paradigm.
- Concurrent merging of quantitative and qualitative research requires greater attention to having adequate sample sizes, using comparable samples, and applying a consistent unit of analysis. For sequential designs where one phase of qualitative research builds on the quantitative phase or vice versa, decisions about what results from the first phase to use in the next phase, the choice of samples and estimating reasonable sample sizes for both phases, and the interpretation of results from both phases can be difficult.
- Due to multiple forms of data being collected and analyzed, this design requires extensive time and resources to carry out the multiple steps involved in data gathering and interpretation.

Observational Design
This type of research design draws a conclusion by comparing subjects against a control group, in cases where the researcher has no control over the experiment. There are two general types of observational designs. In direct observations, people know that you are watching them. Unobtrusive measures involve any method for studying behavior where individuals do not know they are being observed. An observational study allows a useful insight into a phenomenon and avoids the ethical and practical difficulties of setting up a large and cumbersome research project.
- Observational studies are usually flexible and do not necessarily need to be structured around a hypothesis about what you expect to observe [data is emergent rather than pre-existing].
- The researcher is able to collect in-depth information about a particular behavior.
- Can reveal interrelationships among multifaceted dimensions of group interactions.
- You can generalize your results to real life situations.
- Observational research is useful for discovering what variables may be important before applying other methods like experiments.
- Observation research designs account for the complexity of group behaviors.
- Reliability of data is low because seeing behaviors occur over and over again may be a time consuming task and are difficult to replicate.
- In observational research, findings may only reflect a unique sample population and, thus, cannot be generalized to other groups.
- There can be problems with bias as the researcher may only "see what they want to see."
- There is no possibility to determine "cause and effect" relationships since nothing is manipulated.
- Sources or subjects may not all be equally credible.
- Any group that is knowingly studied is altered to some degree by the presence of the researcher, therefore, potentially skewing any data collected.

Philosophical Design
Understood more as an broad approach to examining a research problem than a methodological design, philosophical analysis and argumentation is intended to challenge deeply embedded, often intractable, assumptions underpinning an area of study. This approach uses the tools of argumentation derived from philosophical traditions, concepts, models, and theories to critically explore and challenge, for example, the relevance of logic and evidence in academic debates, to analyze arguments about fundamental issues, or to discuss the root of existing discourse about a research problem. These overarching tools of analysis can be framed in three ways:
- Ontology -- the study that describes the nature of reality; for example, what is real and what is not, what is fundamental and what is derivative?
- Epistemology -- the study that explores the nature of knowledge; for example, by what means does knowledge and understanding depend upon and how can we be certain of what we know?
- Axiology -- the study of values; for example, what values does an individual or group hold and why? How are values related to interest, desire, will, experience, and means-to-end? And, what is the difference between a matter of fact and a matter of value?
- Can provide a basis for applying ethical decision-making to practice.
- Functions as a means of gaining greater self-understanding and self-knowledge about the purposes of research.
- Brings clarity to general guiding practices and principles of an individual or group.
- Philosophy informs methodology.
- Refine concepts and theories that are invoked in relatively unreflective modes of thought and discourse.
- Beyond methodology, philosophy also informs critical thinking about epistemology and the structure of reality (metaphysics).
- Offers clarity and definition to the practical and theoretical uses of terms, concepts, and ideas.
- Limited application to specific research problems [answering the "So What?" question in social science research].
- Analysis can be abstract, argumentative, and limited in its practical application to real-life issues.
- While a philosophical analysis may render problematic that which was once simple or taken-for-granted, the writing can be dense and subject to unnecessary jargon, overstatement, and/or excessive quotation and documentation.
- There are limitations in the use of metaphor as a vehicle of philosophical analysis.
- There can be analytical difficulties in moving from philosophy to advocacy and between abstract thought and application to the phenomenal world.

Sequential Design
- The researcher has a limitless option when it comes to sample size and the sampling schedule.
- Due to the repetitive nature of this research design, minor changes and adjustments can be done during the initial parts of the study to correct and hone the research method.
- This is a useful design for exploratory studies.
- There is very little effort on the part of the researcher when performing this technique. It is generally not expensive, time consuming, or workforce intensive.
- Because the study is conducted serially, the results of one sample are known before the next sample is taken and analyzed. This provides opportunities for continuous improvement of sampling and methods of analysis.
- The sampling method is not representative of the entire population. The only possibility of approaching representativeness is when the researcher chooses to use a very large sample size significant enough to represent a significant portion of the entire population. In this case, moving on to study a second or more specific sample can be difficult.
- The design cannot be used to create conclusions and interpretations that pertain to an entire population because the sampling technique is not randomized. Generalizability from findings is, therefore, limited.
- Difficult to account for and interpret variation from one sample to another over time, particularly when using qualitative methods of data collection.

Systematic Review
- A systematic review synthesizes the findings of multiple studies related to each other by incorporating strategies of analysis and interpretation intended to reduce biases and random errors.
- The application of critical exploration, evaluation, and synthesis methods separates insignificant, unsound, or redundant research from the most salient and relevant studies worthy of reflection.
- They can be use to identify, justify, and refine hypotheses, recognize and avoid hidden problems in prior studies, and explain data inconsistencies and conflicts in data.
- Systematic reviews can be used to help policy makers formulate evidence-based guidelines and regulations.
- The use of strict, explicit, and pre-determined methods of synthesis, when applied appropriately, provide reliable estimates about the effects of interventions, evaluations, and effects related to the overarching research problem investigated by each study under review.
- Systematic reviews illuminate where knowledge or thorough understanding of a research problem is lacking and, therefore, can then be used to guide future research.
- The accepted inclusion of unpublished studies [i.e., grey literature] ensures the broadest possible way to analyze and interpret research on a topic.
- Results of the synthesis can be generalized and the findings extrapolated into the general population with more validity than most other types of studies .
- Systematic reviews do not create new knowledge per se; they are a method for synthesizing existing studies about a research problem in order to gain new insights and determine gaps in the literature.
- The way researchers have carried out their investigations [e.g., the period of time covered, number of participants, sources of data analyzed, etc.] can make it difficult to effectively synthesize studies.
- The inclusion of unpublished studies can introduce bias into the review because they may not have undergone a rigorous peer-review process prior to publication. Examples may include conference presentations or proceedings, publications from government agencies, white papers, working papers, and internal documents from organizations, and doctoral dissertations and Master's theses.

Types of Research – Tips and Examples
Published by Carmen Troy at August 16th, 2021 , Revised On May 8, 2024
“Research is an investigation conducted to seek knowledge and find solutions to scientific and social problems.”
It includes the collection of information from various sources. New research can contribute to existing knowledge.
The types of research can be categorised from the following perspectives;
- Application of the study
- Aim of the research
- Mode of Inquiry
- Research approach
Categories of Research | Types of Research |
---|---|
Types of research according to the application perspective | |
Types of research according to the aims of the research | |
Types of research according to the mode of inquiry | |
Types of research according to the aims of the research approach |
Types of Research According to the Application Perspective
The different types of research, according to the application perspective, include the following.
Basic Research
Primary research is conducted to increase knowledge. It is also known as theoretical research, pure research, and fundamental research. It provides in-depth knowledge about the scientific and logical explanations and their conclusions.
The results of the primary research are used as the base of applied research. It is based on experiments and observation. The results of basic research are published in peer-reviewed journals.
- What is global warming?
- How did the Universe begin?
- What do humans get stress?
Applied Research
Applied research is conducted to find solutions for practical problems. It uses the outcomes of basic research as its base. The results of applied research are applied immediately. It includes case studies and experimental research.
Example: Finding the solution to control air pollution.
Descriptive Research
Descriptive research is carried out to describe current issues and programs and provides information about the issue through surveys and various fact-finding methods.
It includes co-relational and comparative methods of research. It follows the Ex post facto research, which predicts the possible reasons behind the situation that has already occurred.
A researcher cannot control its variables and can report only about the current situation and its occurring.
Example: The widespread contaminated diseases in a specific area of the town. An investigation revealed that there was no trash removal system in that area. A researcher can hypothesise that improper trash removal leads to widespread contaminated diseases.
Analytical Research
In analytical research, a researcher can use the existing data, facts, and knowledge and critically analyse and evaluate the sources and material. It attempts to describe why a specific situation exists.
Example: Impact of video games on teenagers.
Explanatory
Explanatory research is conducted to know why and how two or more variables are interrelated. Researchers usually conduct experiments to know the effect of specific changes among two or more variables.
Example: A study to identify the impact of a nutritious diet on pregnant women.
Exploratory
Exploratory research is conducted to understand the nature of the problem. It does not focus on finding evidence or a conclusion of the problem. It studies the problem to explore the research in-depth and covers topics that have not been studied before.
Example: An investigation into the growing crimes against women in India.

Types of Research According to the Mode of Inquiry
Qualitative research.
Qualitative research is based on quality, and it looks in-depth at non-numerical data. It enables us to understand the comprehensive details of the problem. The researcher prepares open-ended questions to gather as much information as possible.
- Stress level among men and women.
- The obesity rate among teenagers.
Quantitative Research
Quantitative research is associated with the aspects of measurement, quantity, and extent. It follows the statistical, mathematical, and computational techniques in the form of numerical data such as percentages and statistics. The type of research is conducted on a large population.
- Find out the weight of students of the fifth standard
- Studying in government schools.
Types of Research According to the Research Approach
Longitudinal research.
Researchers collect the information at multiple points in time. Usually, a specific group of participants is selected and examined numerous times at various periods.
Example: If a researcher experiments on a group of women to find out the impact of a low-carb diet within six months. The women’s weight and health check-ups will be done multiple times to get the evidence for the study.
Cross-Sectional Research
Cross-sectional research gathers and compares the information from various groups of the population at the same point. It may not provide the exact reason and relationship between the subjects, but it gives a broad picture of studying multiple groups at the same time.
Example: If a researcher wants to know the number of students studying in a school, he will get to know about the age groups, height, weight, and gender of the students at the same time.
Conceptual Research
It is associated with the concept and theory that describes the hypothesis being studied. It is based on the inductive approach of reasoning. It does not follow practical experiments. Philosophers, thinkers, logicians, and theorists use such research to discover new concepts and understand existing knowledge.
Example: Discoveries of Sir Isaac Newton and Einstein.
Empirical Research
It is also known as experimental research, which depends on observation and experience. It is based on the deductive approach of reasoning . A researcher focuses on gathering information about the facts and their sources and investigating the existing knowledge. Example: Is intermittent fasting the healthy weight loss option for women?
The researcher can come up with the result that a certain number of women lost weight, and it improved their health. On the other hand, a certain number of women suffering from low blood pressure and diabetes didn’t lose weight, and they faced the negative impacts of intermittent fasting on their health.

![types of research project work Plagiarism Detector](https://www.researchprospect.com/wp-content/uploads/2021/10/Image-copy-3.png)
Mixed Methods of Research
When you combine quantitative and qualitative methods of research, the resulting approach becomes mixed methods of research.
Over the last few decades, much of the research in the world of academia has been conducted using mixed methods. Due to its greater legitimacy, this particular technique has gained for several reasons, including the feeling that combining the two types of research can provide holistic and more dependable results.
Here is what mixed methods of research involve:
- Interpreting and investigating the information gathered through quantitative and qualitative techniques.
- There could be more than one stage of research. Depending on the topic of research, occasionally, it would be more appropriate to perform qualitative research in the first stage to figure out and investigate a problem to unveil key themes and conduct quantitative research in stage two of the process for measuring relationships between the themes.
Tips for Choosing the Right Type of Research
Choosing the right type of research is essential for producing relevant and actionable insights. The choice depends on your objectives, available resources, and the nature of the problem. Here are some tips to help you make the right decision:
Define your Research Objectives Clearly
- Descriptive Research: To describe the characteristics of certain phenomena.
- Exploratory Research: To explore a problem that hasn’t been studied in depth.
- Explanatory (or Causal) Research: To explain patterns of cause and effect.
- Predictive Research: To forecast future outcomes based on patterns.
Understand the Research Methods
- Quantitative Research: Employs structured data collection (e.g., surveys) to generate statistical data.
- Qualitative Research: Uses unstructured or semi-structured data collection methods (e.g., interviews, observations) to understand behaviour, motivations, etc.
Consider the Time Dimension
- Cross-sectional Studies: Capture data at a single point in time.
- Longitudinal Studies: Collect data over extended periods to observe changes.
Evaluate Available Resources
- Budget: Some research methods, like experimental research, may require more funding.
- Time: Exploratory or ethnographic studies may take longer than surveys.
- Expertise: Ensure you or your team possess the skills needed for your chosen research method.
Consider the Nature of the Problem
Complex problems may require mixed-methods research (a combination of qualitative and quantitative).
Review Existing Literature
Review existing literature before settling on a type to see what methodologies were previously employed for similar questions.
Think about Data Collection
Consider the best method to gather data: surveys, interviews, experiments, observations, etc. Your choice affects the research type.
Ethical Considerations:
Ensure your chosen method abides by ethical standards, especially when human subjects are involved.
Generalisability Vs. Depth
Quantitative methods often allow for generalisability, while qualitative methods provide depth and detail.
Pilot Testing
If unsure, run a pilot study to test your chosen method’s feasibility and utility.
Stay Open to Adaptation
Sometimes, initial research can lead to unforeseen insights or complexities. Be prepared to adjust your approach if needed.
Seek Feedback
Discuss your research approach with colleagues, mentors, or experts in the field. They might offer valuable insights or identify potential pitfalls.
Stay Updated
Research methods evolve. Stay updated with the latest techniques, tools, and best practices in your field.

Research is a systematic inquiry aimed at discovering, interpreting, and revising knowledge about specific phenomena. It involves formulating hypotheses, collecting data, and analysing results to generate new insights or validate existing theories. Conducted in various fields, research can be empirical, theoretical, or experimental and is fundamental for informed decision-making.
What are the different Types of Research?
Different types of research include:
- Descriptive: Describe and analyse phenomena.
- Experimental: Manipulate variables to establish causation.
- Correlational: Examine relationships between variables.
- Qualitative: Gather insights and understanding.
- Quantitative: Use numerical data for analysis.
- Case study, survey, ethnography, and more.
What is research design?
Research design is a structured blueprint for conducting a study, outlining how data will be collected, analysed, and interpreted. It determines the overall strategy and approach to obtain valid, accurate, and reliable results. Research design encompasses choices about type (e.g., experimental, observational), method (qualitative, quantitative), and data collection procedures.
What is survey?
A survey is a research method used to gather data from a predefined group by asking specific questions. Surveys can be conducted using various mediums, such as face-to-face interviews, phone calls, or online questionnaires. They are valuable for collecting descriptive, quantitative, or qualitative information and gauging public opinion or behaviours.
What is research method?
A research method is a systematic approach used by researchers to gather, analyse, and interpret data relevant to their study. It dictates how information is collected and evaluated to answer specific research questions. Methods can be qualitative, quantitative, or mixed and include techniques like surveys, experiments, case studies, and interviews.
What is exploratory research?
Exploratory research is an initial study designed to clarify and define the nature of a problem. It’s used when researchers have a limited understanding of the topic. Instead of seeking definitive answers, it aims to identify patterns, ideas, or hypotheses. Methods often include literature reviews, qualitative interviews, and observational studies.
What is the purpose of research?
The purpose of research is to discover, interpret, or revise knowledge on specific topics or phenomena. It seeks to answer questions, validate theories, or find solutions to problems.

How To Choose Your Research Methodology
Qualitative vs quantitative vs mixed methods.
By: Derek Jansen (MBA). Expert Reviewed By: Dr Eunice Rautenbach | June 2021
Without a doubt, one of the most common questions we receive at Grad Coach is “ How do I choose the right methodology for my research? ”. It’s easy to see why – with so many options on the research design table, it’s easy to get intimidated, especially with all the complex lingo!
In this post, we’ll explain the three overarching types of research – qualitative, quantitative and mixed methods – and how you can go about choosing the best methodological approach for your research.
Overview: Choosing Your Methodology
Understanding the options – Qualitative research – Quantitative research – Mixed methods-based research
Choosing a research methodology – Nature of the research – Research area norms – Practicalities
![research-methodology-webinar-2024 Free Webinar: Research Methodology 101](https://gradcoach.com/wp-content/uploads/research-methodology-webinar-2024.png)
1. Understanding the options
Before we jump into the question of how to choose a research methodology, it’s useful to take a step back to understand the three overarching types of research – qualitative , quantitative and mixed methods -based research. Each of these options takes a different methodological approach.
Qualitative research utilises data that is not numbers-based. In other words, qualitative research focuses on words , descriptions , concepts or ideas – while quantitative research makes use of numbers and statistics. Qualitative research investigates the “softer side” of things to explore and describe, while quantitative research focuses on the “hard numbers”, to measure differences between variables and the relationships between them.
Importantly, qualitative research methods are typically used to explore and gain a deeper understanding of the complexity of a situation – to draw a rich picture . In contrast to this, quantitative methods are usually used to confirm or test hypotheses . In other words, they have distinctly different purposes. The table below highlights a few of the key differences between qualitative and quantitative research – you can learn more about the differences here.
- Uses an inductive approach
- Is used to build theories
- Takes a subjective approach
- Adopts an open and flexible approach
- The researcher is close to the respondents
- Interviews and focus groups are oftentimes used to collect word-based data.
- Generally, draws on small sample sizes
- Uses qualitative data analysis techniques (e.g. content analysis , thematic analysis , etc)
- Uses a deductive approach
- Is used to test theories
- Takes an objective approach
- Adopts a closed, highly planned approach
- The research is disconnected from respondents
- Surveys or laboratory equipment are often used to collect number-based data.
- Generally, requires large sample sizes
- Uses statistical analysis techniques to make sense of the data
Mixed methods -based research, as you’d expect, attempts to bring these two types of research together, drawing on both qualitative and quantitative data. Quite often, mixed methods-based studies will use qualitative research to explore a situation and develop a potential model of understanding (this is called a conceptual framework), and then go on to use quantitative methods to test that model empirically.
In other words, while qualitative and quantitative methods (and the philosophies that underpin them) are completely different, they are not at odds with each other. It’s not a competition of qualitative vs quantitative. On the contrary, they can be used together to develop a high-quality piece of research. Of course, this is easier said than done, so we usually recommend that first-time researchers stick to a single approach , unless the nature of their study truly warrants a mixed-methods approach.
The key takeaway here, and the reason we started by looking at the three options, is that it’s important to understand that each methodological approach has a different purpose – for example, to explore and understand situations (qualitative), to test and measure (quantitative) or to do both. They’re not simply alternative tools for the same job.
Right – now that we’ve got that out of the way, let’s look at how you can go about choosing the right methodology for your research.
![methodology-choices-new Methodology choices in research](https://gradcoach.com/wp-content/uploads/methodology-choices-new.png)
2. How to choose a research methodology
To choose the right research methodology for your dissertation or thesis, you need to consider three important factors . Based on these three factors, you can decide on your overarching approach – qualitative, quantitative or mixed methods. Once you’ve made that decision, you can flesh out the finer details of your methodology, such as the sampling , data collection methods and analysis techniques (we discuss these separately in other posts ).
The three factors you need to consider are:
- The nature of your research aims, objectives and research questions
- The methodological approaches taken in the existing literature
- Practicalities and constraints
Let’s take a look at each of these.
Factor #1: The nature of your research
As I mentioned earlier, each type of research (and therefore, research methodology), whether qualitative, quantitative or mixed, has a different purpose and helps solve a different type of question. So, it’s logical that the key deciding factor in terms of which research methodology you adopt is the nature of your research aims, objectives and research questions .
But, what types of research exist?
Broadly speaking, research can fall into one of three categories:
- Exploratory – getting a better understanding of an issue and potentially developing a theory regarding it
- Confirmatory – confirming a potential theory or hypothesis by testing it empirically
- A mix of both – building a potential theory or hypothesis and then testing it
As a rule of thumb, exploratory research tends to adopt a qualitative approach , whereas confirmatory research tends to use quantitative methods . This isn’t set in stone, but it’s a very useful heuristic. Naturally then, research that combines a mix of both, or is seeking to develop a theory from the ground up and then test that theory, would utilize a mixed-methods approach.
![confirmatory-exploratory-research Exploratory vs confirmatory research](https://gradcoach.com/wp-content/uploads/confirmatory-exploratory-research.png)
Let’s look at an example in action.
If your research aims were to understand the perspectives of war veterans regarding certain political matters, you’d likely adopt a qualitative methodology, making use of interviews to collect data and one or more qualitative data analysis methods to make sense of the data.
If, on the other hand, your research aims involved testing a set of hypotheses regarding the link between political leaning and income levels, you’d likely adopt a quantitative methodology, using numbers-based data from a survey to measure the links between variables and/or constructs .
So, the first (and most important thing) thing you need to consider when deciding which methodological approach to use for your research project is the nature of your research aims , objectives and research questions. Specifically, you need to assess whether your research leans in an exploratory or confirmatory direction or involves a mix of both.
The importance of achieving solid alignment between these three factors and your methodology can’t be overstated. If they’re misaligned, you’re going to be forcing a square peg into a round hole. In other words, you’ll be using the wrong tool for the job, and your research will become a disjointed mess.
If your research is a mix of both exploratory and confirmatory, but you have a tight word count limit, you may need to consider trimming down the scope a little and focusing on one or the other. One methodology executed well has a far better chance of earning marks than a poorly executed mixed methods approach. So, don’t try to be a hero, unless there is a very strong underpinning logic.

Factor #2: The disciplinary norms
Choosing the right methodology for your research also involves looking at the approaches used by other researchers in the field, and studies with similar research aims and objectives to yours. Oftentimes, within a discipline, there is a common methodological approach (or set of approaches) used in studies. While this doesn’t mean you should follow the herd “just because”, you should at least consider these approaches and evaluate their merit within your context.
A major benefit of reviewing the research methodologies used by similar studies in your field is that you can often piggyback on the data collection techniques that other (more experienced) researchers have developed. For example, if you’re undertaking a quantitative study, you can often find tried and tested survey scales with high Cronbach’s alphas. These are usually included in the appendices of journal articles, so you don’t even have to contact the original authors. By using these, you’ll save a lot of time and ensure that your study stands on the proverbial “shoulders of giants” by using high-quality measurement instruments .
Of course, when reviewing existing literature, keep point #1 front of mind. In other words, your methodology needs to align with your research aims, objectives and questions. Don’t fall into the trap of adopting the methodological “norm” of other studies just because it’s popular. Only adopt that which is relevant to your research.
Factor #3: Practicalities
When choosing a research methodology, there will always be a tension between doing what’s theoretically best (i.e., the most scientifically rigorous research design ) and doing what’s practical , given your constraints . This is the nature of doing research and there are always trade-offs, as with anything else.
But what constraints, you ask?
When you’re evaluating your methodological options, you need to consider the following constraints:
- Data access
- Equipment and software
- Your knowledge and skills
Let’s look at each of these.
Constraint #1: Data access
The first practical constraint you need to consider is your access to data . If you’re going to be undertaking primary research , you need to think critically about the sample of respondents you realistically have access to. For example, if you plan to use in-person interviews , you need to ask yourself how many people you’ll need to interview, whether they’ll be agreeable to being interviewed, where they’re located, and so on.
If you’re wanting to undertake a quantitative approach using surveys to collect data, you’ll need to consider how many responses you’ll require to achieve statistically significant results. For many statistical tests, a sample of a few hundred respondents is typically needed to develop convincing conclusions.
So, think carefully about what data you’ll need access to, how much data you’ll need and how you’ll collect it. The last thing you want is to spend a huge amount of time on your research only to find that you can’t get access to the required data.
Constraint #2: Time
The next constraint is time. If you’re undertaking research as part of a PhD, you may have a fairly open-ended time limit, but this is unlikely to be the case for undergrad and Masters-level projects. So, pay attention to your timeline, as the data collection and analysis components of different methodologies have a major impact on time requirements . Also, keep in mind that these stages of the research often take a lot longer than originally anticipated.
Another practical implication of time limits is that it will directly impact which time horizon you can use – i.e. longitudinal vs cross-sectional . For example, if you’ve got a 6-month limit for your entire research project, it’s quite unlikely that you’ll be able to adopt a longitudinal time horizon.
Constraint #3: Money
As with so many things, money is another important constraint you’ll need to consider when deciding on your research methodology. While some research designs will cost near zero to execute, others may require a substantial budget .
Some of the costs that may arise include:
- Software costs – e.g. survey hosting services, analysis software, etc.
- Promotion costs – e.g. advertising a survey to attract respondents
- Incentive costs – e.g. providing a prize or cash payment incentive to attract respondents
- Equipment rental costs – e.g. recording equipment, lab equipment, etc.
- Travel costs
- Food & beverages
These are just a handful of costs that can creep into your research budget. Like most projects, the actual costs tend to be higher than the estimates, so be sure to err on the conservative side and expect the unexpected. It’s critically important that you’re honest with yourself about these costs, or you could end up getting stuck midway through your project because you’ve run out of money.
![research budget Budgeting for your research](https://gradcoach.com/wp-content/uploads/research-budget.png)
Constraint #4: Equipment & software
Another practical consideration is the hardware and/or software you’ll need in order to undertake your research. Of course, this variable will depend on the type of data you’re collecting and analysing. For example, you may need lab equipment to analyse substances, or you may need specific analysis software to analyse statistical data. So, be sure to think about what hardware and/or software you’ll need for each potential methodological approach, and whether you have access to these.
Constraint #5: Your knowledge and skillset
The final practical constraint is a big one. Naturally, the research process involves a lot of learning and development along the way, so you will accrue knowledge and skills as you progress. However, when considering your methodological options, you should still consider your current position on the ladder.
Some of the questions you should ask yourself are:
- Am I more of a “numbers person” or a “words person”?
- How much do I know about the analysis methods I’ll potentially use (e.g. statistical analysis)?
- How much do I know about the software and/or hardware that I’ll potentially use?
- How excited am I to learn new research skills and gain new knowledge?
- How much time do I have to learn the things I need to learn?
Answering these questions honestly will provide you with another set of criteria against which you can evaluate the research methodology options you’ve shortlisted.
So, as you can see, there is a wide range of practicalities and constraints that you need to take into account when you’re deciding on a research methodology. These practicalities create a tension between the “ideal” methodology and the methodology that you can realistically pull off. This is perfectly normal, and it’s your job to find the option that presents the best set of trade-offs.
Recap: Choosing a methodology
In this post, we’ve discussed how to go about choosing a research methodology. The three major deciding factors we looked at were:
- Exploratory
- Confirmatory
- Combination
- Research area norms
- Hardware and software
- Your knowledge and skillset

Research Methodology Types
Types of Research Methodology are as follows:
Quantitative Research Methodology
This is a research methodology that involves the collection and analysis of numerical data using statistical methods. This type of research is often used to study cause-and-effect relationships and to make predictions.
Qualitative Research Methodology
This is a research methodology that involves the collection and analysis of non-numerical data such as words, images, and observations. This type of research is often used to explore complex phenomena, to gain an in-depth understanding of a particular topic, and to generate hypotheses.
Mixed-Methods Research Methodology
This is a research methodology that combines elements of both quantitative and qualitative research. This approach can be particularly useful for studies that aim to explore complex phenomena and to provide a more comprehensive understanding of a particular topic.
Case Study Research Methodology
This is a research methodology that involves in-depth examination of a single case or a small number of cases. Case studies are often used in psychology, sociology, and anthropology to gain a detailed understanding of a particular individual or group.
Action Research Methodology
This is a research methodology that involves a collaborative process between researchers and practitioners to identify and solve real-world problems. Action research is often used in education, healthcare, and social work.
Experimental Research Methodology
This is a research methodology that involves the manipulation of one or more independent variables to observe their effects on a dependent variable. Experimental research is often used to study cause-and-effect relationships and to make predictions.
Survey Research Methodology
This is a research methodology that involves the collection of data from a sample of individuals using questionnaires or interviews. Survey research is often used to study attitudes, opinions, and behaviors.
Grounded Theory Research Methodology
This is a research methodology that involves the development of theories based on the data collected during the research process. Grounded theory is often used in sociology and anthropology to generate theories about social phenomena.
Research Methodology Example
An Example of Research Methodology could be the following:
Research Methodology for Investigating the Effectiveness of Cognitive Behavioral Therapy in Reducing Symptoms of Depression in Adults
Introduction:
The aim of this research is to investigate the effectiveness of cognitive-behavioral therapy (CBT) in reducing symptoms of depression in adults. To achieve this objective, a randomized controlled trial (RCT) will be conducted using a mixed-methods approach.
Research Design:
The study will follow a pre-test and post-test design with two groups: an experimental group receiving CBT and a control group receiving no intervention. The study will also include a qualitative component, in which semi-structured interviews will be conducted with a subset of participants to explore their experiences of receiving CBT.
Participants:
Participants will be recruited from community mental health clinics in the local area. The sample will consist of 100 adults aged 18-65 years old who meet the diagnostic criteria for major depressive disorder. Participants will be randomly assigned to either the experimental group or the control group.
Intervention :
The experimental group will receive 12 weekly sessions of CBT, each lasting 60 minutes. The intervention will be delivered by licensed mental health professionals who have been trained in CBT. The control group will receive no intervention during the study period.
Data Collection:
Quantitative data will be collected through the use of standardized measures such as the Beck Depression Inventory-II (BDI-II) and the Generalized Anxiety Disorder-7 (GAD-7). Data will be collected at baseline, immediately after the intervention, and at a 3-month follow-up. Qualitative data will be collected through semi-structured interviews with a subset of participants from the experimental group. The interviews will be conducted at the end of the intervention period, and will explore participants’ experiences of receiving CBT.
Data Analysis:
Quantitative data will be analyzed using descriptive statistics, t-tests, and mixed-model analyses of variance (ANOVA) to assess the effectiveness of the intervention. Qualitative data will be analyzed using thematic analysis to identify common themes and patterns in participants’ experiences of receiving CBT.
Ethical Considerations:
This study will comply with ethical guidelines for research involving human subjects. Participants will provide informed consent before participating in the study, and their privacy and confidentiality will be protected throughout the study. Any adverse events or reactions will be reported and managed appropriately.
Data Management:
All data collected will be kept confidential and stored securely using password-protected databases. Identifying information will be removed from qualitative data transcripts to ensure participants’ anonymity.
Limitations:
One potential limitation of this study is that it only focuses on one type of psychotherapy, CBT, and may not generalize to other types of therapy or interventions. Another limitation is that the study will only include participants from community mental health clinics, which may not be representative of the general population.
Conclusion:
This research aims to investigate the effectiveness of CBT in reducing symptoms of depression in adults. By using a randomized controlled trial and a mixed-methods approach, the study will provide valuable insights into the mechanisms underlying the relationship between CBT and depression. The results of this study will have important implications for the development of effective treatments for depression in clinical settings.

Choosing the Right Research Methodology: A Guide for Researchers
- 3 minute read
- 51.2K views
Table of Contents
Choosing an optimal research methodology is crucial for the success of any research project. The methodology you select will determine the type of data you collect, how you collect it, and how you analyse it. Understanding the different types of research methods available along with their strengths and weaknesses, is thus imperative to make an informed decision.
Understanding different research methods:
There are several research methods available depending on the type of study you are conducting, i.e., whether it is laboratory-based, clinical, epidemiological, or survey based . Some common methodologies include qualitative research, quantitative research, experimental research, survey-based research, and action research. Each method can be opted for and modified, depending on the type of research hypotheses and objectives.
Qualitative vs quantitative research:
When deciding on a research methodology, one of the key factors to consider is whether your research will be qualitative or quantitative. Qualitative research is used to understand people’s experiences, concepts, thoughts, or behaviours . Quantitative research, on the contrary, deals with numbers, graphs, and charts, and is used to test or confirm hypotheses, assumptions, and theories.
Qualitative research methodology:
Qualitative research is often used to examine issues that are not well understood, and to gather additional insights on these topics. Qualitative research methods include open-ended survey questions, observations of behaviours described through words, and reviews of literature that has explored similar theories and ideas. These methods are used to understand how language is used in real-world situations, identify common themes or overarching ideas, and describe and interpret various texts. Data analysis for qualitative research typically includes discourse analysis, thematic analysis, and textual analysis.
Quantitative research methodology:
The goal of quantitative research is to test hypotheses, confirm assumptions and theories, and determine cause-and-effect relationships. Quantitative research methods include experiments, close-ended survey questions, and countable and numbered observations. Data analysis for quantitative research relies heavily on statistical methods.
Analysing qualitative vs quantitative data:
The methods used for data analysis also differ for qualitative and quantitative research. As mentioned earlier, quantitative data is generally analysed using statistical methods and does not leave much room for speculation. It is more structured and follows a predetermined plan. In quantitative research, the researcher starts with a hypothesis and uses statistical methods to test it. Contrarily, methods used for qualitative data analysis can identify patterns and themes within the data, rather than provide statistical measures of the data. It is an iterative process, where the researcher goes back and forth trying to gauge the larger implications of the data through different perspectives and revising the analysis if required.
When to use qualitative vs quantitative research:
The choice between qualitative and quantitative research will depend on the gap that the research project aims to address, and specific objectives of the study. If the goal is to establish facts about a subject or topic, quantitative research is an appropriate choice. However, if the goal is to understand people’s experiences or perspectives, qualitative research may be more suitable.
Conclusion:
In conclusion, an understanding of the different research methods available, their applicability, advantages, and disadvantages is essential for making an informed decision on the best methodology for your project. If you need any additional guidance on which research methodology to opt for, you can head over to Elsevier Author Services (EAS). EAS experts will guide you throughout the process and help you choose the perfect methodology for your research goals.

Research Methods | Definition, Types, Examples
Research methods are specific procedures for collecting and analysing data. Developing your research methods is an integral part of your research design . When planning your methods, there are two key decisions you will make.
First, decide how you will collect data . Your methods depend on what type of data you need to answer your research question :
- Qualitative vs quantitative : Will your data take the form of words or numbers?
- Primary vs secondary : Will you collect original data yourself, or will you use data that have already been collected by someone else?
- Descriptive vs experimental : Will you take measurements of something as it is, or will you perform an experiment?
Second, decide how you will analyse the data .
- For quantitative data, you can use statistical analysis methods to test relationships between variables.
- For qualitative data, you can use methods such as thematic analysis to interpret patterns and meanings in the data.

Data are the information that you collect for the purposes of answering your research question . The type of data you need depends on the aims of your research.
Qualitative vs quantitative data
Your choice of qualitative or quantitative data collection depends on the type of knowledge you want to develop.
For questions about ideas, experiences and meanings, or to study something that can’t be described numerically, collect qualitative data .
If you want to develop a more mechanistic understanding of a topic, or your research involves hypothesis testing , collect quantitative data .

Quantitative | . |
You can also take a mixed methods approach, where you use both qualitative and quantitative research methods.
Primary vs secondary data
Primary data are any original information that you collect for the purposes of answering your research question (e.g. through surveys , observations and experiments ). Secondary data are information that has already been collected by other researchers (e.g. in a government census or previous scientific studies).
If you are exploring a novel research question, you’ll probably need to collect primary data. But if you want to synthesise existing knowledge, analyse historical trends, or identify patterns on a large scale, secondary data might be a better choice.
Primary | ||

Secondary |
Descriptive vs experimental data
In descriptive research , you collect data about your study subject without intervening. The validity of your research will depend on your sampling method .
In experimental research , you systematically intervene in a process and measure the outcome. The validity of your research will depend on your experimental design .
To conduct an experiment, you need to be able to vary your independent variable , precisely measure your dependent variable, and control for confounding variables . If it’s practically and ethically possible, this method is the best choice for answering questions about cause and effect.

Research method | Primary or secondary? | Qualitative or quantitative? | When to use |
---|---|---|---|
Primary | Quantitative | To test cause-and-effect relationships. | |
Primary | Quantitative | To understand general characteristics of a population. | |
Interview/focus group | Primary | Qualitative | To gain more in-depth understanding of a topic. |
Observation | Primary | Either | To understand how something occurs in its natural setting. |
Secondary | Either | To situate your research in an existing body of work, or to evaluate trends within a research topic. | |
Either | Either | To gain an in-depth understanding of a specific group or context, or when you don’t have the resources for a large study. |
Your data analysis methods will depend on the type of data you collect and how you prepare them for analysis.
Data can often be analysed both quantitatively and qualitatively. For example, survey responses could be analysed qualitatively by studying the meanings of responses or quantitatively by studying the frequencies of responses.
Qualitative analysis methods
Qualitative analysis is used to understand words, ideas, and experiences. You can use it to interpret data that were collected:
- From open-ended survey and interview questions, literature reviews, case studies, and other sources that use text rather than numbers.
- Using non-probability sampling methods .
Qualitative analysis tends to be quite flexible and relies on the researcher’s judgement, so you have to reflect carefully on your choices and assumptions.
Quantitative analysis methods
Quantitative analysis uses numbers and statistics to understand frequencies, averages and correlations (in descriptive studies) or cause-and-effect relationships (in experiments).
You can use quantitative analysis to interpret data that were collected either:
- During an experiment.
- Using probability sampling methods .
Because the data are collected and analysed in a statistically valid way, the results of quantitative analysis can be easily standardised and shared among researchers.
Research method | Qualitative or quantitative? | When to use |
---|---|---|
Quantitative | To analyse data collected in a statistically valid manner (e.g. from experiments, surveys, and observations). | |
Meta-analysis | Quantitative | To statistically analyse the results of a large collection of studies. Can only be applied to studies that collected data in a statistically valid manner. |
Qualitative | To analyse data collected from interviews, focus groups or textual sources. To understand general themes in the data and how they are communicated. | |
Either | To analyse large volumes of textual or visual data collected from surveys, literature reviews, or other sources. Can be quantitative (i.e. frequencies of words) or qualitative (i.e. meanings of words). |
Quantitative research deals with numbers and statistics, while qualitative research deals with words and meanings.
Quantitative methods allow you to test a hypothesis by systematically collecting and analysing data, while qualitative methods allow you to explore ideas and experiences in depth.
In mixed methods research , you use both qualitative and quantitative data collection and analysis methods to answer your research question .
A sample is a subset of individuals from a larger population. Sampling means selecting the group that you will actually collect data from in your research.
For example, if you are researching the opinions of students in your university, you could survey a sample of 100 students.
Statistical sampling allows you to test a hypothesis about the characteristics of a population. There are various sampling methods you can use to ensure that your sample is representative of the population as a whole.
The research methods you use depend on the type of data you need to answer your research question .
- If you want to measure something or test a hypothesis , use quantitative methods . If you want to explore ideas, thoughts, and meanings, use qualitative methods .
- If you want to analyse a large amount of readily available data, use secondary data. If you want data specific to your purposes with control over how they are generated, collect primary data.
- If you want to establish cause-and-effect relationships between variables , use experimental methods. If you want to understand the characteristics of a research subject, use descriptive methods.
Methodology refers to the overarching strategy and rationale of your research project . It involves studying the methods used in your field and the theories or principles behind them, in order to develop an approach that matches your objectives.
Methods are the specific tools and procedures you use to collect and analyse data (e.g. experiments, surveys , and statistical tests ).
In shorter scientific papers, where the aim is to report the findings of a specific study, you might simply describe what you did in a methods section .
In a longer or more complex research project, such as a thesis or dissertation , you will probably include a methodology section , where you explain your approach to answering the research questions and cite relevant sources to support your choice of methods.

Writing a research report is part of most university degrees, so it is essential you know what one is and how to write one. This guide on how to do a research project for your university degree shows you what to do at each stage, taking you from planning to finishing the project.
What is a research project?
The big question is: what is a research project? A research project for students is an extended essay that presents a question or statement for analysis and evaluation. During a research project, you will present your own ideas and research on a subject alongside analysing existing knowledge.
How to write a research report
The next section covers the research project steps necessary to producing a research paper.
Developing a research question or statement
Research project topics will vary depending on the course you study. The best research project ideas develop from areas you already have an interest in and where you have existing knowledge.
The area of study needs to be specific as it will be much easier to cover fully. If your topic is too broad, you are at risk of not having an in-depth project. You can, however, also make your topic too narrow and there will not be enough research to be done. To make sure you don’t run into either of these problems, it’s a great idea to create sub-topics and questions to ensure you are able to complete suitable research.
A research project example question would be: How will modern technologies change the way of teaching in the future?
Finding and evaluating sources
Secondary research is a large part of your research project as it makes up the literature review section. It is essential to use credible sources as failing to do so may decrease the validity of your research project.
Examples of secondary research include:
- Peer-reviewed journals
- Scholarly articles
- Newspapers
Great places to find your sources are the University library and Google Scholar. Both will give you many opportunities to find the credible sources you need. However, you need to make sure you are evaluating whether they are fit for purpose before including them in your research project as you do not want to include out of date information.
When evaluating sources, you need to ask yourself:
- Is the information provided by an expert?
- How well does the source answer the research question?
- What does the source contribute to its field?
- Is the source valid? e.g. does it contain bias and is the information up-to-date?
It is important to ensure that you have a variety of sources in order to avoid bias. A successful research paper will present more than one point of view and the best way to do this is to not rely too heavily on just one author or publication.
Conducting research
For a research project, you will need to conduct primary research. This is the original research you will gather to further develop your research project. The most common types of primary research are interviews and surveys as these allow for many and varied results.
Examples of primary research include:
- Interviews and surveys
- Focus groups
- Experiments
- Research diaries
If you are looking to study in the UK and have an interest in bettering your research skills, The University of Sheffield is a world top 100 research university which will provide great research opportunities and resources for your project.
Research report format
Now that you understand the basics of how to write a research project, you now need to look at what goes into each section. The research project format is just as important as the research itself. Without a clear structure you will not be able to present your findings concisely.
A research paper is made up of seven sections: introduction, literature review, methodology, findings and results, discussion, conclusion, and references. You need to make sure you are including a list of correctly cited references to avoid accusations of plagiarism.
Introduction
The introduction is where you will present your hypothesis and provide context for why you are doing the project. Here you will include relevant background information, present your research aims and explain why the research is important.
Literature review
The literature review is where you will analyse and evaluate existing research within your subject area. This section is where your secondary research will be presented. A literature review is an integral part of your research project as it brings validity to your research aims.
What to include when writing your literature review:
- A description of the publications
- A summary of the main points
- An evaluation on the contribution to the area of study
- Potential flaws and gaps in the research
Methodology
The research paper methodology outlines the process of your data collection. This is where you will present your primary research. The aim of the methodology section is to answer two questions:
- Why did you select the research methods you used?
- How do these methods contribute towards your research hypothesis?
In this section you will not be writing about your findings, but the ways in which you are going to try and achieve them. You need to state whether your methodology will be qualitative, quantitative, or mixed.
- Qualitative – first hand observations such as interviews, focus groups, case studies and questionnaires. The data collected will generally be non-numerical.
- Quantitative – research that deals in numbers and logic. The data collected will focus on statistics and numerical patterns.
- Mixed – includes both quantitative and qualitative research.
The methodology section should always be written in the past tense, even if you have already started your data collection.
Findings and results
In this section you will present the findings and results of your primary research. Here you will give a concise and factual summary of your findings using tables and graphs where appropriate.
Discussion
The discussion section is where you will talk about your findings in detail. Here you need to relate your results to your hypothesis, explaining what you found out and the significance of the research.
It is a good idea to talk about any areas with disappointing or surprising results and address the limitations within the research project. This will balance your project and steer you away from bias.
Some questions to consider when writing your discussion:
- To what extent was the hypothesis supported?
- Was your research method appropriate?
- Was there unexpected data that affected your results?
- To what extent was your research validated by other sources?
Conclusion
The conclusion is where you will bring your research project to a close. In this section you will not only be restating your research aims and how you achieved them, but also discussing the wider significance of your research project. You will talk about the successes and failures of the project, and how you would approach further study.
It is essential you do not bring any new ideas into your conclusion; this section is used only to summarise what you have already stated in the project.
References
As a research project is your own ideas blended with information and research from existing knowledge, you must include a list of correctly cited references. Creating a list of references will allow the reader to easily evaluate the quality of your secondary research whilst also saving you from potential plagiarism accusations.
The way in which you cite your sources will vary depending on the university standard.
If you are an international student looking to study a degree in the UK , The University of Sheffield International College has a range of pathway programmes to prepare you for university study. Undertaking a Research Project is one of the core modules for the Pre-Masters programme at The University of Sheffield International College.
Frequently Asked Questions
What is the best topic for research .
It’s a good idea to choose a topic you have existing knowledge on, or one that you are interested in. This will make the research process easier; as you have an idea of where and what to look for in your sources, as well as more enjoyable as it’s a topic you want to know more about.
What should a research project include?
There are seven main sections to a research project, these are:
- Introduction – the aims of the project and what you hope to achieve
- Literature review – evaluating and reviewing existing knowledge on the topic
- Methodology – the methods you will use for your primary research
- Findings and results – presenting the data from your primary research
- Discussion – summarising and analysing your research and what you have found out
- Conclusion – how the project went (successes and failures), areas for future study
- List of references – correctly cited sources that have been used throughout the project.
How long is a research project?
The length of a research project will depend on the level study and the nature of the subject. There is no one length for research papers, however the average dissertation style essay can be anywhere from 4,000 to 15,000+ words.

What is Research Methodology? Definition, Types, and Examples
![title= types of research project work](https://pp-blog.paperpal.com/wp-content/uploads/2023/07/pexels-ketut-subiyanto-4559602-1170x780.jpg)
Research methodology 1,2 is a structured and scientific approach used to collect, analyze, and interpret quantitative or qualitative data to answer research questions or test hypotheses. A research methodology is like a plan for carrying out research and helps keep researchers on track by limiting the scope of the research. Several aspects must be considered before selecting an appropriate research methodology, such as research limitations and ethical concerns that may affect your research.
The research methodology section in a scientific paper describes the different methodological choices made, such as the data collection and analysis methods, and why these choices were selected. The reasons should explain why the methods chosen are the most appropriate to answer the research question. A good research methodology also helps ensure the reliability and validity of the research findings. There are three types of research methodology—quantitative, qualitative, and mixed-method, which can be chosen based on the research objectives.
What is research methodology ?
A research methodology describes the techniques and procedures used to identify and analyze information regarding a specific research topic. It is a process by which researchers design their study so that they can achieve their objectives using the selected research instruments. It includes all the important aspects of research, including research design, data collection methods, data analysis methods, and the overall framework within which the research is conducted. While these points can help you understand what is research methodology, you also need to know why it is important to pick the right methodology.
![types of research project work Paperpal your AI academic writing assistant](https://pp-blog.paperpal.com/wp-content/uploads/2023/03/RPaperpal_BlogBanners-1_02_.png)
Having a good research methodology in place has the following advantages: 3
- Helps other researchers who may want to replicate your research; the explanations will be of benefit to them.
- You can easily answer any questions about your research if they arise at a later stage.
- A research methodology provides a framework and guidelines for researchers to clearly define research questions, hypotheses, and objectives.
- It helps researchers identify the most appropriate research design, sampling technique, and data collection and analysis methods.
- A sound research methodology helps researchers ensure that their findings are valid and reliable and free from biases and errors.
- It also helps ensure that ethical guidelines are followed while conducting research.
- A good research methodology helps researchers in planning their research efficiently, by ensuring optimum usage of their time and resources.

Types of research methodology.
There are three types of research methodology based on the type of research and the data required. 1
- Quantitative research methodology focuses on measuring and testing numerical data. This approach is good for reaching a large number of people in a short amount of time. This type of research helps in testing the causal relationships between variables, making predictions, and generalizing results to wider populations.
- Qualitative research methodology examines the opinions, behaviors, and experiences of people. It collects and analyzes words and textual data. This research methodology requires fewer participants but is still more time consuming because the time spent per participant is quite large. This method is used in exploratory research where the research problem being investigated is not clearly defined.
- Mixed-method research methodology uses the characteristics of both quantitative and qualitative research methodologies in the same study. This method allows researchers to validate their findings, verify if the results observed using both methods are complementary, and explain any unexpected results obtained from one method by using the other method.
What are the types of sampling designs in research methodology?
Sampling 4 is an important part of a research methodology and involves selecting a representative sample of the population to conduct the study, making statistical inferences about them, and estimating the characteristics of the whole population based on these inferences. There are two types of sampling designs in research methodology—probability and nonprobability.
- Probability sampling
In this type of sampling design, a sample is chosen from a larger population using some form of random selection, that is, every member of the population has an equal chance of being selected. The different types of probability sampling are:
- Systematic —sample members are chosen at regular intervals. It requires selecting a starting point for the sample and sample size determination that can be repeated at regular intervals. This type of sampling method has a predefined range; hence, it is the least time consuming.
- Stratified —researchers divide the population into smaller groups that don’t overlap but represent the entire population. While sampling, these groups can be organized, and then a sample can be drawn from each group separately.
- Cluster —the population is divided into clusters based on demographic parameters like age, sex, location, etc.
- Convenience —selects participants who are most easily accessible to researchers due to geographical proximity, availability at a particular time, etc.
- Purposive —participants are selected at the researcher’s discretion. Researchers consider the purpose of the study and the understanding of the target audience.
- Snowball —already selected participants use their social networks to refer the researcher to other potential participants.
- Quota —while designing the study, the researchers decide how many people with which characteristics to include as participants. The characteristics help in choosing people most likely to provide insights into the subject.
What are data collection methods?
During research, data are collected using various methods depending on the research methodology being followed and the research methods being undertaken. Both qualitative and quantitative research have different data collection methods, as listed below.
Qualitative research 5
- One-on-one interviews: Helps the interviewers understand a respondent’s subjective opinion and experience pertaining to a specific topic or event
- Document study/literature review/record keeping: Researchers’ review of already existing written materials such as archives, annual reports, research articles, guidelines, policy documents, etc.
- Focus groups: Constructive discussions that usually include a small sample of about 6-10 people and a moderator, to understand the participants’ opinion on a given topic.
- Qualitative observation : Researchers collect data using their five senses (sight, smell, touch, taste, and hearing).
Quantitative research 6
- Sampling: The most common type is probability sampling.
- Interviews: Commonly telephonic or done in-person.
- Observations: Structured observations are most commonly used in quantitative research. In this method, researchers make observations about specific behaviors of individuals in a structured setting.
- Document review: Reviewing existing research or documents to collect evidence for supporting the research.
- Surveys and questionnaires. Surveys can be administered both online and offline depending on the requirement and sample size.

What are data analysis methods.
The data collected using the various methods for qualitative and quantitative research need to be analyzed to generate meaningful conclusions. These data analysis methods 7 also differ between quantitative and qualitative research.
Quantitative research involves a deductive method for data analysis where hypotheses are developed at the beginning of the research and precise measurement is required. The methods include statistical analysis applications to analyze numerical data and are grouped into two categories—descriptive and inferential.
Descriptive analysis is used to describe the basic features of different types of data to present it in a way that ensures the patterns become meaningful. The different types of descriptive analysis methods are:
- Measures of frequency (count, percent, frequency)
- Measures of central tendency (mean, median, mode)
- Measures of dispersion or variation (range, variance, standard deviation)
- Measure of position (percentile ranks, quartile ranks)
Inferential analysis is used to make predictions about a larger population based on the analysis of the data collected from a smaller population. This analysis is used to study the relationships between different variables. Some commonly used inferential data analysis methods are:
- Correlation: To understand the relationship between two or more variables.
- Cross-tabulation: Analyze the relationship between multiple variables.
- Regression analysis: Study the impact of independent variables on the dependent variable.
- Frequency tables: To understand the frequency of data.
- Analysis of variance: To test the degree to which two or more variables differ in an experiment.
Qualitative research involves an inductive method for data analysis where hypotheses are developed after data collection. The methods include:
- Content analysis: For analyzing documented information from text and images by determining the presence of certain words or concepts in texts.
- Narrative analysis: For analyzing content obtained from sources such as interviews, field observations, and surveys. The stories and opinions shared by people are used to answer research questions.
- Discourse analysis: For analyzing interactions with people considering the social context, that is, the lifestyle and environment, under which the interaction occurs.
- Grounded theory: Involves hypothesis creation by data collection and analysis to explain why a phenomenon occurred.
- Thematic analysis: To identify important themes or patterns in data and use these to address an issue.
How to choose a research methodology?
Here are some important factors to consider when choosing a research methodology: 8
- Research objectives, aims, and questions —these would help structure the research design.
- Review existing literature to identify any gaps in knowledge.
- Check the statistical requirements —if data-driven or statistical results are needed then quantitative research is the best. If the research questions can be answered based on people’s opinions and perceptions, then qualitative research is most suitable.
- Sample size —sample size can often determine the feasibility of a research methodology. For a large sample, less effort- and time-intensive methods are appropriate.
- Constraints —constraints of time, geography, and resources can help define the appropriate methodology.

By SHANNON O. WELLS
In the brilliant sunlight of a late summer afternoon at Hazelwood Green by the Monongahela River, even the weathered old shell of the former Jones & Laughlin Steel factory — with the help of thousands of solar panels up top — looms majestically amid the site’s mix of fresh landscaping, open spaces and construction zones as a tour group strolls around the once-fallow former industrial site.
While the popular phrase “eds and meds” describing Pittsburgh’s transition from manufacturing giant to a university- and medical center-fueled hub suggests the latter supplanted the former, Pitt’s fledgling BioForge project is aimed toward bringing together the city’s history of product creation with its more recent flair for cutting-edge innovation.
On Sept. 5, a group of about two dozen folks from Pitt and the surrounding Hazelwood neighborhood got a sneak preview of the 185,000-gross-square-foot BioForge life-sciences manufacturing center now being constructed on 3.5 acres of the former steel-making property.
The event was held ahead of a topping-off ceremony for the building on Friday morning.
“I first heard about BioForge when I was a candidate for chancellor, and it is one of the main reasons that I am here in this role,” Pitt Chancellor Joan Gabel said at the Sept. 6 ceremony. “Because when you look at what a research university can do in terms of discovery, in terms of advancing science, in terms of advancing therapies and cures, in terms of economic development, in terms of partnering with a community in service or in terms of just being vibrant and exciting and inspiring as a place to live and learn and work — there’s really nothing like this anywhere, and I wanted to be a part of it.”
On Thursday, Heidi Ward, director of planning for Pitt’s Neighborhood Commitment in Hazelwood, guided a walking tour through the expansive site. The couple dozen neighbors and Pitt representatives on the tour were given an opportunity to sign the final construction beam that was put in place Friday morning.
The $250 million BioForge project will share Hazelwood Green with existing facilities including the Advanced Manufacturing Research Center, Motional driverless vehicles, and Carnegie Mellon University’s Robotics Innovation Center as well as proposed residential housing development to create a more well-rounded neighborhood mix.
“In addition to our greater Hazelwood neighborhood commitment, the University of Pittsburgh is developing a new biomanufacturing facility called the BioForge,” Ward explained. “This catalytic development is why we continue to hear the term life sciences … the field of study that helps us learn about our health, really how we can coexist and have a better, more thriving world together.”
First announced in fall 2021, the BioForge project’s exterior construction is scheduled to be complete in the first half of 2025. When the project is complete, probably by the summer 2026, it’s expected to create around 830 jobs.
Therapies within reach
![Ken Gabriel, founding director of BioForge’s Advanced Biomanufacturing Institute, talks to media after the topping off ceremony for the new building. (Aimee Obidzinski | University of Pittsburgh) Man speaking to reporters](https://www.utimes.pitt.edu/sites/default/files/090624/Bioforge_Beam_Gabriel.jpg)
Currently overseeing design and construction of the facility, Ken Gabriel, a former engineering professor at Carnegie Mellon University who serves as founding director of BioForge’s Advanced Biomanufacturing Institute, will direct operations as chief executive officer of the life-sciences manufacturing center. He described the significance and opportunity BioForge represents for Pitt as well as the once-blighted property it will occupy.
BioForge, he noted, will innovate in the subset of therapy known as precision medicine.
“And the basic idea of precision biologic medicine is that the best therapy for you — the best medicine for you — is you,” Gabriel explained. “And what I mean by that is your own body being helped to fight a disease or overcome a condition. And these types of precision biological medicines are relatively new. We’ve been hearing a lot about them.
“They fall under the category of cell and gene therapy, or RNA, which some of you may have experienced, like we all did as a (COVID) vaccine,” he added, “but these are the types of new therapies that actually help your body heal itself.”
As promising and exciting as these are, including regular news articles celebrating breakthroughs like “(deaf) children who can hear again,” or patients “overcoming cancer of the blood, in particular through these sort of treatments,” there’s still the not-so-little matter of affordability.
“By the time you get to page three or the seventh screen of that article, they tell you the therapy costs $3 million or $2.5 million dollars, half the cost of putting up solar panels here,” he observed. “That’s not within reach of the people who need it. It’s barely a drop in the bucket to address the number of people who need these sorts of treatments.”
BioForge, therefore, is designed to seek and create breakthroughs and innovations in manufacturing precision biological medicines to accelerate their delivery and use.
“That’s our whole focus and point. And we’re going to focus like a laser beam,” Gabriel said. “We don’t need more science. That’s already happening at the University of Pittsburgh. There’s tons of money in the private sector that’s ready to come in to invest.”
Closing the gap
Before BioForge, Gabriel served as founding chief operating officer of Wellcome Leap, an organization that combined life sciences and engineering to deliver critical medical innovations at accelerated timescales. In just over two years, the organization launched 10 ongoing programs ranging from artificial kidneys and depression biology to next-generation surgical delivery and resilient aging.
He also worked as president and CEO of Draper, an engineering spin-off of the Massachusetts Institute of Technology, as corporate vice president and founding co-lead of the Advanced Technology and Projects group at Google, and as acting director of the Defense Advanced Research Projects Agency at the U.S. Department of Defense.
“What BioForge is going to do is close that gap between where these technologies get through in the laboratory and where they need to be, in terms of manufacturing and repeatability, so that we can get it out to everyone equitably and as fast as possible,” Gabriel added on the Hazelwood Green tour. “It’s not going to be easy.”
What he finds encouraging, however, is the innovation that already surrounds the BioForge site. Synergy among the facilities will be a key element of BioForge’s ability to thrive.
“The building of BioForge is over there, where we’re going to be focusing on the manufacturing and the life sciences and the biology needed,” he said, gesturing south toward the river, where construction is underway. “But right next to us is the manufacturing of futures. Right over there is Robotics Innovation Center …
“In order to do the manufacturing advances that we need, we need automation. We need machine learning. We need robotics, not just by itself, but working together with the life sciences,” he added. “So this is putting us, as a region, very well positioned to do this in a way that gets precision biological medicines out and delivers on the promising potential and makes it real.”
A neighborly place
As part of the site tour, Heidi Ward provided historical information on the roller-coaster history of Hazelwood Green, which once was considered part of the Squirrel Hill neighborhood. Noting a long population decline, she said 2020 census data indicates 4,548 residents live in greater Hazelwood.
“And when we compare it to a city, the population in greater Hazelwood really is overrepresented by those that are under the age of 18 and those that are over the age of 65,” she said. “As a dear friend, Sonia Tillman, once said to me, ‘Hazelwood is like a barbell — one side is really the youth and the other side is our older citizens, and so we have very few people that are actually in that working population.”
Pointing toward green space on the southwest section of the Hazelwood Green site, Ward explained the housing component of the redevelopment project that will be completed in three separate phases.
“It really will be multi-family development. The first phase will have 50 units (with 27) reserved as ‘affordable,’” she said. “The other 13 units will be set aside for families that are involved in the Pittsburgh Scholar House,” a project designed to improve the quality of life for single parents and their children through post-secondary education and supportive services.
“I think all of us are really looking forward to housing coming here in the development,” she added.
More than 1,000 greater Hazelwood residents came together to help create a neighborhood plan, “to really share what they wanted to see happen to this neighborhood after the steel mill collapsed,” Ward said. “The plan focuses on ways to strengthen and improve the community while proactively preparing for future growth and change as the neighborhood continues to evolve.
“The community will use its plan to ensure it remains an inclusive, family friendly neighborhood that recognizes that its greatest asset is its people — all of you.”

Major Research Instrumentation Program (MRI)
View guidelines, important information about nsf’s implementation of the revised 2 cfr.
NSF Financial Assistance awards (grants and cooperative agreements) made on or after October 1, 2024, will be subject to the applicable set of award conditions, dated October 1, 2024, available on the NSF website . These terms and conditions are consistent with the revised guidance specified in the OMB Guidance for Federal Financial Assistance published in the Federal Register on April 22, 2024.
Important information for proposers
All proposals must be submitted in accordance with the requirements specified in this funding opportunity and in the NSF Proposal & Award Policies & Procedures Guide (PAPPG) that is in effect for the relevant due date to which the proposal is being submitted. It is the responsibility of the proposer to ensure that the proposal meets these requirements. Submitting a proposal prior to a specified deadline does not negate this requirement.
Supports requests for up to $4 million from NSF for the development or acquisition of multi-user research instruments that are critical to the advancement of science and engineering.
Instrument Acquisition or Development
The Major Research Instrumentation (MRI) Program ( MRI Program Website) serves to increase access to multi-user scientific and engineering instrumentation for research and research training in our Nation's institutions of higher education and not-for-profit scientific/engineering research organizations. An MRI award supports the acquisition of a multi-user research instrument that is commercially available through direct purchase from a vendor, or for the personnel costs and equipment that are required for the development of an instrument with new capabilities, thereby advancing instrumentation capabilities and enhancing expertise for instrument design and fabrication at academic institutions. MRI instruments are, in general, too costly and/or not appropriate for support through other NSF programs.
MRI provides support to acquire critical research instrumentation without which advances in fundamental science and engineering research may not otherwise occur. MRI also provides support to obtain next-generation research instruments by developing instruments with new capabilities that open new opportunities to advance the frontiers in science and engineering research. Additionally, an MRI award is expected to enhance research training of students who will become the next generation of instrument users, designers and builders.
An MRI proposal may request from NSF up to $4 million for either acquisition or development of a research instrument. Each performing organization may submit in revised "Tracks" as defined below, with no more than two (2) submissions in Track 1 and no more than one (1) submission in Track 2 . For the newly defined Track 3, no more than one (1) submission per competition is permitted. As a result, it is now possible for an institution to submit up to four MRI proposals within the Track limits as described above.
- Track 1: Track 1 MRI proposals are those that request funds from NSF greater than $100,000 [1] and less than $1,400,000.
- Track 2: Track 2 MRI proposals are those that request funds from NSF greater than or equal to $1,400,000 up to and including $4,000,000.
- Track 3: Track 3 MRI proposals are those that request funds from NSF greater than or equal to $100,000 [1] and less than or equal to $4,000,000 that include the purchase, installation, operation, and maintenance of equipment and instrumentation to conserve or reduce the consumption of helium. Institutions may submit no more than one Track 3 proposal. Submission of a Track 3 proposal does not impact limits that apply for Track 1 and Track 2 proposals.
Cost sharing requirements for new awards in the MRI Program are waived for a period of 5 years beginning with the FY 2023 MRI competition. Institutional submission limits for Track 1, Track 2 and Track 3 proposals remain.
The MRI Program especially seeks broad representation of groups, institutions, and geographic regions that are underrepresented in STEM disciplines. Proposals from women, underrepresented minorities, persons with disabilities and early-career PIs are encouraged, as are proposals that benefit early-career researchers and proposals with PIs from geographically underserved regions, including EPSCoR jurisdictions. Additionally, proposals are encouraged from under-resourced institutions, including from emerging research institutions, where MRI can significantly build capacity for research.
___________________________
[1] Track 1 proposals requesting funds from NSF less than $100,000 will be accepted only from: a) eligible performing organizations requesting instrumentation supporting research in the disciplines of mathematics or social, behavioral and economic sciences; or b) non-Ph.D.-granting institutions of higher education requesting instrumentation supporting research in any NSF-supported disciplines.

Frequently asked questions
What is a research project.
A research project is an academic, scientific, or professional undertaking to answer a research question . Research projects can take many forms, such as qualitative or quantitative , descriptive , longitudinal , experimental , or correlational . What kind of research approach you choose will depend on your topic.
Frequently asked questions: Writing a research paper
The best way to remember the difference between a research plan and a research proposal is that they have fundamentally different audiences. A research plan helps you, the researcher, organize your thoughts. On the other hand, a dissertation proposal or research proposal aims to convince others (e.g., a supervisor, a funding body, or a dissertation committee) that your research topic is relevant and worthy of being conducted.
Formulating a main research question can be a difficult task. Overall, your question should contribute to solving the problem that you have defined in your problem statement .
However, it should also fulfill criteria in three main areas:
- Researchability
- Feasibility and specificity
- Relevance and originality
Research questions anchor your whole project, so it’s important to spend some time refining them.
In general, they should be:
- Focused and researchable
- Answerable using credible sources
- Complex and arguable
- Feasible and specific
- Relevant and original
All research questions should be:
- Focused on a single problem or issue
- Researchable using primary and/or secondary sources
- Feasible to answer within the timeframe and practical constraints
- Specific enough to answer thoroughly
- Complex enough to develop the answer over the space of a paper or thesis
- Relevant to your field of study and/or society more broadly
![types of research project work Writing Strong Research Questions](https://www.scribbr.com/wp-content/uploads/2022/10/Characteristics-of-a-strong-research-question-Scribbr-small-1.webp)
A research aim is a broad statement indicating the general purpose of your research project. It should appear in your introduction at the end of your problem statement , before your research objectives.
Research objectives are more specific than your research aim. They indicate the specific ways you’ll address the overarching aim.
Once you’ve decided on your research objectives , you need to explain them in your paper, at the end of your problem statement .
Keep your research objectives clear and concise, and use appropriate verbs to accurately convey the work that you will carry out for each one.
I will compare …
Your research objectives indicate how you’ll try to address your research problem and should be specific:
Research objectives describe what you intend your research project to accomplish.
They summarize the approach and purpose of the project and help to focus your research.
Your objectives should appear in the introduction of your research paper , at the end of your problem statement .
The main guidelines for formatting a paper in Chicago style are to:
- Use a standard font like 12 pt Times New Roman
- Use 1 inch margins or larger
- Apply double line spacing
- Indent every new paragraph ½ inch
- Include a title page
- Place page numbers in the top right or bottom center
- Cite your sources with author-date citations or Chicago footnotes
- Include a bibliography or reference list
To automatically generate accurate Chicago references, you can use Scribbr’s free Chicago reference generator .
The main guidelines for formatting a paper in MLA style are as follows:
- Use an easily readable font like 12 pt Times New Roman
- Set 1 inch page margins
- Include a four-line MLA heading on the first page
- Center the paper’s title
- Use title case capitalization for headings
- Cite your sources with MLA in-text citations
- List all sources cited on a Works Cited page at the end
To format a paper in APA Style , follow these guidelines:
- Use a standard font like 12 pt Times New Roman or 11 pt Arial
- If submitting for publication, insert a running head on every page
- Apply APA heading styles
- Cite your sources with APA in-text citations
- List all sources cited on a reference page at the end
No, it’s not appropriate to present new arguments or evidence in the conclusion . While you might be tempted to save a striking argument for last, research papers follow a more formal structure than this.
All your findings and arguments should be presented in the body of the text (more specifically in the results and discussion sections if you are following a scientific structure). The conclusion is meant to summarize and reflect on the evidence and arguments you have already presented, not introduce new ones.
The conclusion of a research paper has several key elements you should make sure to include:
- A restatement of the research problem
- A summary of your key arguments and/or findings
- A short discussion of the implications of your research
Don’t feel that you have to write the introduction first. The introduction is often one of the last parts of the research paper you’ll write, along with the conclusion.
This is because it can be easier to introduce your paper once you’ve already written the body ; you may not have the clearest idea of your arguments until you’ve written them, and things can change during the writing process .
The way you present your research problem in your introduction varies depending on the nature of your research paper . A research paper that presents a sustained argument will usually encapsulate this argument in a thesis statement .
A research paper designed to present the results of empirical research tends to present a research question that it seeks to answer. It may also include a hypothesis —a prediction that will be confirmed or disproved by your research.
The introduction of a research paper includes several key elements:
- A hook to catch the reader’s interest
- Relevant background on the topic
- Details of your research problem
and your problem statement
- A thesis statement or research question
- Sometimes an overview of the paper
