The methodology section explains how you did your research. It describes the design, sample, materials, procedure, and analysis in enough detail that a competent reader could replicate or fairly evaluate your study. Done well, the methodology turns a personal investigation into a defensible piece of scholarship.
Most students lose marks here not because their research is bad, but because the description is vague. "We surveyed some students" is not a methodology - it's a hint. This guide breaks down the standard structure, gives you templates for both quantitative and qualitative research, and shows side-by-side strong and weak examples so you can see exactly what works.

Start WritingWhat is a Methodology Section?
A methodology section is the part of a research paper or thesis that explains how the research was carried out and why those choices were appropriate. It is not a chronological diary - it is a justified description of the design and procedures.
Two questions guide every sentence in the section:
- What did you do? - The concrete steps, sample, instruments, and analysis.
- Why did you do it that way? - The justification for each choice, ideally tied to prior literature.
If a sentence answers neither question, cut it.
Methodology vs Methods: Are They the Same?
The two terms are often used interchangeably, but they aren't quite the same:
- Methods = the specific tools and techniques used (e.g. semi-structured interviews, t-tests).
- Methodology = the overall logic of the research design and the reasoning behind those methods.
Many universities use "methodology section" as a label for the chapter that covers both. Always check your assignment brief.
The Standard Structure of a Methodology Section
Most methodology sections follow this seven-part structure. Quantitative and qualitative studies use the same skeleton with different content.
- Research design - the overall approach (experiment, survey, case study, ethnography, etc.).
- Participants or sample - who or what you studied, sample size, and how you recruited them.
- Materials or instruments - questionnaires, interview guides, datasets, equipment.
- Procedure - the steps you actually took, in chronological order.
- Data analysis - how you processed and interpreted the data.
- Ethical considerations - consent, confidentiality, IRB / ethics approval.
- Limitations of the design - any constraints baked into the method itself.
Universities and journals vary slightly. Health sciences often add reporting standards (CONSORT, PRISMA). Humanities papers may compress this into one or two paragraphs. Always confirm what is expected.

Full Methodology Examples (Strong vs Weak)
Example 1: Quantitative - Mindfulness and Exam Anxiety
Weak version:
We did a study about mindfulness and exam anxiety. Some students were given mindfulness training while others were not. We then measured their anxiety levels and compared the two groups. The results were analysed using statistics in SPSS. Ethical approval was obtained.
Why it's weak: No design name, no sample size, no recruitment method, no instrument, no analysis specified, vague software claim, no ethics body or reference. A reviewer cannot replicate or even fairly evaluate this study.
Strong version:
This study used a parallel-group randomised controlled trial to test whether a 4-week mindfulness program reduced exam anxiety in undergraduates. 120 students from a UK Russell Group university were recruited via course mailing lists; eligibility required being enrolled in a Year 2 module with an end-of-semester exam and not currently practicing meditation. Participants were randomly allocated using a computer-generated sequence to either the mindfulness intervention (n = 60) or a wait-list control (n = 60). The intervention consisted of four weekly 60-minute sessions delivered in person by a certified MBSR instructor. Anxiety was measured using the State-Trait Anxiety Inventory (STAI; Spielberger, 1983), administered one week before and one week after the program. Group differences were analysed using independent-samples t-tests in R 4.4, with effect sizes reported as Cohen's d. The study received ethical approval from the institutional Research Ethics Committee (ref: REC-2025-118), and all participants gave written informed consent.
Why it works: Named design, named population, sample size, named eligibility criteria, named instrument with citation, software version, named analysis, ethics reference, and informed consent. Each choice is specific and traceable.
Example 2: Qualitative - Doctoral Supervision Experiences
Weak version:
This research interviewed PhD students about their supervisors. We asked them about their experiences and what they felt. The interviews were transcribed and themes were identified. The findings are presented in the next chapter.
Why it's weak: No methodology named, no sample size or sampling logic, no interview structure, no analytic framework, no trustworthiness claim. The reader has no way to evaluate whether the conclusions are justified.
Strong version:
This study used reflexive thematic analysis (Braun & Clarke, 2019) to explore how second-year doctoral students make sense of their supervisory relationships. Twelve participants from social-science PhD programs at three UK universities were recruited through purposive sampling, with maximum variation across discipline, gender, and supervision model (single vs joint). Semi-structured interviews of 60-90 minutes were conducted online via Zoom between January and March 2026, guided by an eight-question protocol developed from prior literature on supervisory power and care. Interviews were audio recorded with consent, transcribed verbatim, and pseudonymised. Coding was conducted in NVivo 14 by the lead researcher, with 20% of transcripts double-coded by a second researcher to support reflexive triangulation. The analysis followed Braun and Clarke's six-phase process; initial codes were generated inductively, then organised into candidate themes through iterative review. To support trustworthiness, a reflexive journal was kept throughout, and provisional themes were shared with three participants for member checking. The study was approved by the institutional Research Ethics Committee (ref: REC-2026-014).
Why it works: Named methodology with citation, sampling logic and variation criteria, mode and duration of interviews, named software, double-coding for trustworthiness, member checking, and ethics reference.
Common Methodology Mistakes (And How to Fix Them)
Mistake 1: No Justification for Choices
Problem: "We used a survey." Why a survey and not interviews? Why this survey and not another?
Fix: For every major choice, add one sentence of justification, ideally tied to prior literature: "A cross-sectional survey was selected to capture attitudes across a large, geographically dispersed sample, following the approach of Smith and Lee (2023)."
Mistake 2: Mixing Methods and Results
Problem: The methodology slips into findings: "We found that participants were more anxious before exams than after."
Fix: The methodology only describes how you collected and analysed data. All findings belong in the results section, with no exceptions.
Mistake 3: Vague Sample Description
Problem: "Participants were university students." How many? What kind? How recruited?
Fix: Always state sample size, key demographics relevant to the question, eligibility criteria, and recruitment route. "Sixty undergraduates (M_age = 20.4, SD = 1.8; 65% female) were recruited via course mailing lists at a single UK university."
Mistake 4: Wrong Tense
Problem: "We will distribute the survey to 200 students" - written after the data has already been collected.
Fix: Use past tense for what you did ("We distributed..."). Use present tense only for stable facts about instruments ("The STAI consists of 20 items").
Mistake 5: No Ethics Statement
Problem: The study collected data from people but the methodology never mentions consent or approval.
Fix: Include a short ethics paragraph: approving body, reference number, consent procedure, anonymisation, and data storage. Even small student projects need this.
Mistake 6: Hiding Limitations of the Design
Problem: The methodology presents the design as flawless and pretends there were no trade-offs.
Fix: Briefly acknowledge constraints baked into the method (e.g., self-report bias, single-site sample). This shows methodological awareness rather than weakness.
How to Write the Methodology: A 6-Step Process
Step 1: List Every Decision You Made
Open a blank page and list every choice: design, sample size, recruitment, instruments, procedure, analysis, ethics. This becomes your skeleton.
Step 2: Justify Each Decision
Next to each decision, write one sentence answering "why?". If you cannot justify it, that's a sign to revisit it - or at least flag it as a limitation.
Step 3: Order the Section Chronologically Where Possible
Within each subsection (especially procedure), describe steps in the order they happened. This is the easiest order for the reader to verify.
Step 4: Use the Right Level of Detail
The test is replicability: could someone else, with reasonable skills, run a comparable study from your description? Too much detail (font size on the questionnaire) is filler. Too little detail (just "a survey") is opaque.
Step 5: Cite Methodological Sources
Methods, frameworks, and validated instruments must be cited. Ad-hoc methods are acceptable when justified, but should also reference comparable approaches.
Step 6: Write the Limitations Last
End with two or three sentences acknowledging design constraints. Save full discussion of implications for the discussion section.
Discipline-Specific Tips
Sciences and Engineering
Be reproducible to the parameter level. Include equipment models, calibration steps, software versions, and data formats. Reporting standards (CONSORT for trials, PRISMA for reviews) are often expected.
Social Sciences
Justify the design and sampling logic explicitly. Validated instruments must be cited; new instruments must include reliability/validity evidence.
Qualitative Research (any discipline)
Name the methodology (thematic analysis, IPA, grounded theory, ethnography), the sampling strategy, and the trustworthiness measures. Reflexivity belongs here, not just in the discussion.
Humanities
The methodology may be a single section or short paragraph identifying the corpus, archive, theoretical framework, and mode of analysis (close reading, discourse analysis, archival research).
FAQs About the Methodology Section
How long should the methodology be?
Usually 10-15% of total word count. For a typical 10,000-word thesis, that's 1,000-1,500 words. Empirical theses with complex designs may justify more.
What tense should I use?
Past tense for what you did. Present tense for stable descriptions of instruments and frameworks.
Do I need to cite my methods?
Yes. Validated instruments, analytic frameworks, and design choices should all be cited. New methods need a comparable reference and justification.
How do I describe a mixed-methods study?
State the overall mixed-methods design (sequential, concurrent, embedded), then describe the quantitative and qualitative strands separately, then briefly explain how the strands are integrated.
Can I use first person ("we" / "I")?
Increasingly yes, especially in social sciences. Some journals still prefer passive voice. Be consistent throughout the section.
What if my method is unusual or ad hoc?
Justify it explicitly. Cite the closest comparable approach, explain why standard methods did not fit, and acknowledge the trade-off in your limitations.
A good methodology earns trust. Spend the time on it - it pays back across every section that follows.
