What the Methodology Section Is For
The methodology section answers one question: how did you get your results? It is the part of a research paper that lets another researcher repeat your study, judge whether your findings are trustworthy, and decide whether your conclusions follow from what you actually did. Everything else in the paper — the introduction, the results, the discussion — depends on it.
Students often treat the methods section as a chore, a dry list of procedures to get through before the interesting part. That is a mistake. Markers and peer reviewers read it closely, because a strong argument built on a weak method collapses. A clear, honest methodology is what turns a collection of findings into research — and it follows a predictable pattern, so once you know it, writing the section becomes a matter of working through it carefully, one decision at a time.
Where the Methodology Section Goes
In a standard research paper, the methodology comes after the introduction and literature review, and before the results. In an IMRaD paper — Introduction, Methods, Results, and Discussion — it is the “M”. In a dissertation, the same material usually becomes a full methodology chapter, which we cover in our dissertation methodology chapter guide. The section is usually written in the past tense, because it describes what you did, and in a formal, impersonal style — “participants were recruited” rather than “I recruited participants” — though conventions vary by discipline, so check a recent paper in your target journal.
What to Include: The 6 Core Elements
Every methodology section needs the same building blocks, whether the study is a survey of 400 students or a close reading of three novels. The proportions change; the elements do not. The University of Southern California Libraries’ guide to writing the methodology section sets out the same core components and is a useful reference if you want a second view.
1. Research design
Start by naming your overall approach. Is the study qualitative, quantitative, or mixed methods? Is it experimental, a survey, a case study, or a systematic review? State the design in the first paragraph and explain, in one or two sentences, why it fits your research question. A reader should be able to see the connection immediately: this question needed this approach.
2. Participants or data sources
Describe who or what you studied, in enough detail for the reader to judge how far the findings travel. For human participants, give the sample size, how they were recruited, and the relevant characteristics — age range, year of study, programme, and any inclusion or exclusion criteria. For secondary data, name the dataset, the time period it covers, and how you accessed it. Be specific about numbers: “forty-two second-year psychology undergraduates were recruited through the department’s participant pool between January and March 2026” tells the reader almost everything they need; “participants were recruited from a university” tells them nothing. If you are writing a research paper for the first time, our guide to writing a strong research question will help you check that your sample actually matches the question you are asking.
3. Materials and instruments
Describe the tools you used to collect data: questionnaires, interview guides, observation checklists, lab equipment, software. For a questionnaire, state the number of items, the response scale, and whether it was adapted from an existing instrument — and if so, cite it. For interviews, say whether they were structured, semi-structured or unstructured, how long they lasted, and whether they were recorded and transcribed. If you designed your own instrument, say so, and describe how you checked it — a pilot test with a small group, feedback from a supervisor, or a reliability check such as Cronbach’s alpha.
4. Procedure
Walk the reader through what happened, step by step, in chronological order. How were participants approached? What instructions did they receive? In what order did the tasks happen? How long did each stage take? Include the practical details that matter for replication: the setting, the timing, the software version, the exact wording of a key instruction if it could have shaped the results.
5. Data analysis
Explain how you turned raw data into findings. For quantitative work, name the statistical tests, the software and version, and the significance level you used. For qualitative work, name the analytical approach — thematic analysis, grounded theory, discourse analysis — and describe the coding process: who coded, whether coding was checked by a second person, and how disagreements were resolved. Do not just name the test; say why it was the right test for your data.
6. Ethical considerations
State whether ethical approval was obtained and from which body, and note the approval reference number if you have one. Describe how consent was obtained, how anonymity and confidentiality were protected, and how participants could withdraw.
Methodology Section Example
Participants. Sixty-four first-year business students at a UK university took part. Thirty-two students in two seminar groups received structured peer feedback on two drafts; the remaining 32, in two comparable seminar groups, received tutor feedback only. Groups were matched on prior attainment using first-semester essay marks.
Procedure. Over eight weeks, both groups completed the same two essay assignments. The peer-feedback group used a structured feedback sheet covering argument, evidence and referencing. All essays were marked blind by two markers using the department’s standard rubric.
Data analysis. Essay marks were compared using an independent-samples t-test (SPSS v29), with significance set at p < .05. Feedback sheets were analysed thematically to identify the kinds of comments students found most useful.
Notice how each paragraph does one job, and how the whole section could be followed by another researcher without guessing.
Quantitative vs Qualitative Methodology: What Changes
The structure above works for both traditions, but the emphasis shifts. In a quantitative methods section, the reader expects precise detail about sampling, measurement, and statistics — sample size calculations, reliability coefficients, the exact test and why it was chosen. Numbers do the persuading. In a qualitative methods section, the reader expects detail about the interpretive process instead — how participants were selected, how themes were developed and checked, and how the researcher handled their own assumptions.
Common Methodology Mistakes
Writing it like a lab diary
“First I did this, then I did that, then I realised I should have done something else.” A methodology section is not a diary of your process. It is a cleaned-up, logical account of the method as it was finally carried out. Mention a pilot study or a change of plan only if it affected the final design.
Leaving out the justification
Every methodological choice needs a reason. Why this sample size? Why this instrument? Why this test? Students often describe what they did and forget to say why — and the “why” is what convinces the reader the method was sound. A single sentence of justification per choice is usually enough.
Being vague about numbers
“Several participants”, “a number of interviews”, “most students agreed”. Vague quantities make a methodology section unverifiable. Give exact numbers wherever you can: sample size, response rate, number of items, duration, dates.
Including results
The methodology section describes what you did, not what you found. Do not report findings here — not even a hint. “The survey showed that most students preferred group work” belongs in the results section. Our guide to writing a research paper discussion section covers what happens after the results are in.
Copying the method from another paper
It is fine — expected, even — to follow established procedures and cite them. It is not fine to copy another paper’s methods section and change the numbers. Your method must describe your study, with your sample, your setting, your instruments. Markers spot borrowed methods quickly, usually because the details do not match the rest of the paper.
How Long Should the Methodology Section Be?
There is no fixed length, but a useful guide is 15–20% of the paper. A 4,000-word research paper gets a methods section of roughly 600–800 words. The deciding factor is not word count but completeness: could another researcher repeat the study from your description? If yes, it is long enough. If no, it is not.
Short papers sometimes fold the methods into a single long paragraph. That is acceptable for a brief empirical report, but for anything longer, use subheadings — Research Design, Participants, Procedure, Data Analysis — to help the reader navigate. Subheadings also help you check that nothing is missing: if you cannot fill in one of the six elements above, that is a gap in the study, not just a gap in the writing.
Final Thoughts
The methodology section is where your research paper earns its credibility. A reader who trusts your method will trust your results; a reader who cannot follow your method will doubt everything that follows. Write it as if a sceptical colleague will try to repeat your study from your description alone — because that is exactly what the section is for. Work through the six elements in order, justify each choice, give exact numbers, and keep the results out.
