What Is a Research Methodology? | Steps & Tips
Your research methodology discusses and explains the data collection and analysis methods you used in your research. A key part of your thesis, dissertation, or research paper, the methodology chapter explains what you did and how you did it, allowing readers to evaluate the reliability and validity of your research.
It should include:
- The type of research you conducted
- How you collected and analysed your data
- Any tools or materials you used in the research
- Why you chose these methods

How to write a research methodology
Why is a methods section important?
Your methods section is your opportunity to share how you conducted your research and why you chose the methods you chose. It’s also the place to show that your research was rigorously conducted and can be replicated.
It gives your research legitimacy and situates it within your field, and also gives your readers a place to refer to if they have any questions or critiques in other sections.
Step 1: Explain your methodological approach
You can start by introducing your overall approach to your research. You have two options here.
Option 1: Start with your “what”
What research problem or question did you investigate?
- Aim to describe the characteristics of something?
- Explore an under-researched topic?
- Establish a causal relationship?
And what type of data did you need to achieve this aim?
- Quantitative data, qualitative data, or a mix of both?
- Primary data collected yourself, or secondary data collected by someone else?
- Experimental data gathered by controlling and manipulating variables, or descriptive data gathered via observations?
Option 2: Start with your “why”
Depending on your discipline, you can also start with a discussion of the rationale and assumptions underpinning your methodology. In other words, why did you choose these methods for your study?
- Why is this the best way to answer your research question?
- Is this a standard methodology in your field, or does it require justification?
- Were there any ethical considerations involved in your choices?
- What are the criteria for validity and reliability in this type of research?
Step 2: Describe your data collection methods
Once you have introduced your reader to your methodological approach, you should share full details about your data collection methods.
In order to be considered generalisable, you should describe quantitative research methods in enough detail for another researcher to replicate your study.
Here, explain how you operationalised your concepts and measured your variables. Discuss your sampling method or inclusion/exclusion criteria, as well as any tools, procedures, and materials you used to gather your data.
Describe where, when, and how the survey was conducted.
- How did you design the questionnaire?
- What form did your questions take (e.g., multiple choice, Likert scale)?
- Were your surveys conducted in-person or virtually?
- What sampling method did you use to select participants?
- What was your sample size and response rate?
Share full details of the tools, techniques, and procedures you used to conduct your experiment.
- How did you design the experiment?
- How did you recruit participants?
- How did you manipulate and measure the variables?
- What tools did you use?
Explain how you gathered and selected the material (such as datasets or archival data) that you used in your analysis.
- Where did you source the material?
- How was the data originally produced?
- What criteria did you use to select material (e.g., date range)?
In qualitative research, methods are often more flexible and subjective. For this reason, it’s crucial to robustly explain the methodology choices you made.
Be sure to discuss the criteria you used to select your data, the context in which your research was conducted, and the role you played in collecting your data (e.g., were you an active participant, or a passive observer?)
Interviews or focus groups
Describe where, when, and how the interviews were conducted.
- How did you find and select participants?
- How many participants took part?
- What form did the interviews take (structured, semi-structured, or unstructured)?
- How long were the interviews?
- How were they recorded?
Describe where, when, and how you conducted the observation or ethnography.
- What group or community did you observe? How long did you spend there?
- How did you gain access to this group? What role did you play in the community?
- How long did you spend conducting the research? Where was it located?
- How did you record your data (e.g., audiovisual recordings, note-taking)?
Explain how you selected case study materials for your analysis.
- What type of materials did you analyse?
- How did you select them?
Mixed methods research combines quantitative and qualitative approaches. If a standalone quantitative or qualitative study is insufficient to answer your research question, mixed methods may be a good fit for you.
Mixed methods are less common than standalone analyses, largely because they require a great deal of effort to pull off successfully. If you choose to pursue mixed methods, it’s especially important to robustly justify your methods here.
Step 3: Describe your analysis method
Next, you should indicate how you processed and analysed your data. Avoid going into too much detail: you should not start introducing or discussing any of your results at this stage.
In quantitative research, your analysis will be based on numbers. In your methods section, you can include:
- How you prepared the data before analysing it (e.g., checking for missing data, removing outliers, transforming variables)
- Which software you used (e.g., SPSS, Stata or R)
- Which statistical tests you used (e.g., two-tailed t test, simple linear regression)
In qualitative research, your analysis will be based on language, images, and observations (often involving some form of textual analysis).
Specific methods might include:
- Content analysis: Categorising and discussing the meaning of words, phrases and sentences
- Thematic analysis: Coding and closely examining the data to identify broad themes and patterns
- Discourse analysis: Studying communication and meaning in relation to their social context
Mixed methods combine the above two research methods, integrating both qualitative and quantitative approaches into one coherent analytical process.
Step 4: Evaluate and justify the methodological choices you made
Above all, your methodology section should clearly make the case for why you chose the methods you did. This is especially true if you did not take the most standard approach to your topic. In this case, discuss why other methods were not suitable for your objectives, and show how this approach contributes new knowledge or understanding.
In any case, it should be overwhelmingly clear to your reader that you set yourself up for success in terms of your methodology’s design. Show how your methods should lead to results that are valid and reliable, while leaving the analysis of the meaning, importance, and relevance of your results for your discussion section.
Tips for writing a strong methodology chapter
Remember that your aim is not just to describe your methods, but to show how and why you applied them. Again, it’s critical to demonstrate that your research was rigorously conducted and can be replicated.
1. Focus on your objectives and research questions
The methodology section should clearly show why your methods suit your objectives and convince the reader that you chose the best possible approach to answering your problem statement and research questions.
2. Cite relevant sources
Your methodology can be strengthened by referencing existing research in your field. This can help you to:
- Show that you followed established practice for your type of research
- Discuss how you decided on your approach by evaluating existing research
- Present a novel methodological approach to address a gap in the literature
3. Write for your audience
Consider how much information you need to give, and avoid getting too lengthy. If you are using methods that are standard for your discipline, you probably don’t need to give a lot of background or justification.
Regardless, your methodology should be a clear, well-structured text that makes an argument for your approach, not just a list of technical details and procedures.
Frequently asked questions about methodology
- What’s the difference between method and methodology?
Methodology refers to the overarching strategy and rationale of your research. Developing your methodology involves studying the research methods used in your field and the theories or principles that underpin them, in order to choose the approach that best matches your objectives.
- Where does the methodology section go?
- What’s the difference between quantitative and qualitative methods?
- What is sampling?
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.
