How To Write A Research Methodology: 8 Best Steps

Sampling Strategy

Explains how participants or data sources are selected — probability or non-probability sampling.

Data Collection & Analysis

Details tools and analytical techniques used to process and interpret data.

Ethical Considerations

Ensures participant consent, confidentiality, and compliance with institutional ethics.

Step 1: Restate Your Research Problem

Your methodology begins with a restatement of your research problem. This section reminds readers of your study’s focus and justifies why specific research methods are necessary. It connects the “what” (research question) to the “how” (methods).

(Creswell & Creswell, 2018)

Example:
If your research question is “What factors influence student motivation in online learning?”, restate it and clarify that your methodology will identify and analyze those influencing factors through surveys and interviews.

Step 2: Explain Your Methodological Approach

The research approach determines how you will gather and analyze data:

Quantitative: Uses measurable data and statistics to test hypotheses.
Qualitative: Explores perceptions and experiences through non-numerical data.
Mixed-Method: Combines both for richer insight.

(Silverman, 2020)

Example:
A study on customer satisfaction might use a quantitative approach with numerical surveys, while research on employee experiences could use qualitative interviews to capture narratives.

Step 3: Describe Your Research Design

Your research design outlines the structure of your study—the blueprint that guides data collection and analysis.
Common designs include:

Experimental: Tests cause-and-effect relationships (e.g., testing the impact of a new drug).
Descriptive: Observes and records existing conditions (e.g., a case study of community behavior).
Exploratory: Investigates new or less-understood areas (e.g., emerging social trends).
Explanatory: Clarifies relationships between variables.

(Kothari, 2014)

Example:
A study examining the impact of music on concentration might use an experimental design, dividing participants into groups listening to different music genres.

Step 4: Define Your Sampling Strategy

A sampling strategy determines how you select participants or data sources.

Probability Sampling: Randomized selection ensures equal representation (e.g., random sampling of university students).
Non-Probability Sampling: Selection based on specific criteria (e.g., purposive sampling of experienced teachers).

(Etikan & Bala, 2017)

Example:
In a study on teacher burnout, purposive sampling ensures that participants are qualified educators with at least 5 years’ experience.

Step 5: Describe Your Data Collection Methods

This section details the data collection tools and procedures used to gather data.

Quantitative: Surveys, questionnaires, and standardized tests.
Qualitative: Interviews, focus groups, observations, and document analysis.
Secondary Data: Pre-existing datasets, archival records, or official statistics.

(Flick, 2018)

Example:
A mixed-method study on public health awareness might combine surveys (quantitative) with follow-up interviews (qualitative) for a deeper context.

Step 6: Explain Your Data Analysis Methods

Data analysis explains how you converted raw data into meaningful results.

Quantitative: Statistical analysis (e.g., regression, t-tests, ANOVA) using SPSS or R.
Qualitative: Thematic analysis or content analysis using NVivo or Atlas. Ti.
Mixed-Method: Merges statistical trends with narrative interpretation.

(Braun & Clarke, 2006)

Example:
A researcher studying gender bias in hiring could use content analysis to code language patterns in job postings and perform frequency analysis on recurring terms.

Step 7: Address Ethical Considerations

Ethical compliance is essential in academic research. It protects participants and upholds institutional standards.

Include:

Informed Consent: Participants understand the study and agree voluntarily.
Confidentiality: Data is anonymized and securely stored.
Integrity: Avoid plagiarism, fabrication, or data manipulation.

(British Psychological Society, 2021)

Example:
In a study that interviews patients about their medical experiences, the researchers obtain written consent and anonymize all identifiers before publication.

Step 8: Acknowledge Limitations

Acknowledging limitations demonstrates transparency and strengthens credibility. Discuss factors that might affect validity, such as sample size, time constraints, or response bias.

(Creswell & Creswell, 2018)

Example:
A survey limited to a single university may not reflect national trends, but triangulating data across multiple sources improves reliability.

FAQs

What is the difference between research methods and methodology?

Research methods are the specific tools and techniques used to collect and analyze data (e.g., surveys and interviews). At the same time, methodology is the overarching framework that justifies the choice and combination of those methods.

How long should a research methodology be?

For most master’s and PhD theses, the methodology chapter typically ranges from 1,500 to 3,000 words, depending on the complexity of the research design and the number of methods used.

What tense should I use in the methodology section?

Since the methodology describes completed work, it should be written in the past tense (e.g., “Data were collected…” instead of “Data are collected…”).

Conclusion

A well-written research methodology provides a clear, logical framework for how your study was designed and executed. It demonstrates that your methods are valid, ethical, and capable of addressing your research questions.

When carefully justified and properly cited, your methodology adds depth, reliability, and scholarly value to your dissertation or thesis.

🧩 Key Takeaway

A strong research methodology explains what you did, how you did it, and why you did it that way. It ensures your study is valid, ethical, and replicable.

Restate your research problem clearly.
Justify your methods and data choices.
Address ethical and practical limitations.

Use established frameworks and cite authoritative sources to strengthen your methodological rigor.
