Research Methodology: Types, Methods & Examples

Strong research methodology convinces reviewers that your findings deserve trust. In plain language, this guide covers how methodology differs from methods, the main paradigms, quantitative, qualitative and mixed approaches, common designs, sampling, data collection, analysis and quality criteria, and it follows one research problem through three different methodologies.

Understanding Research Methodology

Research methodology is the overarching strategy and logic of how a study is conducted: why a certain approach, design, sample, data collection and analysis were chosen, and why they can answer your research question. It captures the “why” and reasoning of the research, rather than only a list of procedures. Reviewers read this reasoning to decide whether your conclusions follow from your evidence.

Methodology vs Methods

If you need help writing up the procedures, read how to write the methods section. Here the focus is on how to choose them.

A Short Guide to Research Paradigms

Many journal papers skip a long discussion of paradigms, but theses normally include one. Knowing your own helps you justify your choices consistently.

Kinds of Research Methodology

• Quantitative: uses numbers and statistics to measure variables and test hypotheses.
• Qualitative: examines experiences, meanings and processes using words, observation and documents.
• Mixed methods: merges the two, for instance by running a survey and then interviews (explanatory sequential), or interviews and then a survey (exploratory sequential).

Research may also be grouped by purpose — exploratory, descriptive, explanatory or evaluative — and by timing: cross-sectional (a single point in time) or longitudinal (repeated over time).

Research Designs

Sampling

Justify the sample size in quantitative studies (for example through a power calculation). In qualitative studies, explain how you judged that you had enough data, such as reaching thematic saturation. Whatever the approach, report the reasoning so readers can judge whether the sample suits the claims.

Data Collection Methods

• Questionnaires and surveys — structured and scalable, but the instrument needs validating.
• Interviews and focus groups — detailed and rich; record, transcribe and analyse them systematically.
• Observation — watching behaviour in its natural setting.
• Measurements and experiments — instruments, calibration and protocols.
• Documents and secondary data — records, archives and datasets that already exist.

Data Analysis

Analysis in quantitative work runs from descriptive statistics to tests such as t-tests, ANOVA, chi-square, correlation and regression. Qualitative analysis covers thematic analysis, content analysis and grounded theory. Studies using mixed methods also require an integration step explaining how the two strands inform one another. Settle the analysis plan before you collect data.

Ensuring Validity, Reliability and Trustworthiness

Worked Example: Three Methodologies for One Problem

Invented problem: “What leads some village households to leave their drinking water untreated?”

No single one is “best”: the right choice depends on your question and your available resources.

Choosing Your Methodology

1. Formulate a precise research question.
2. Decide which type of evidence would answer it.
3. Pick the design able to produce that evidence.
4. Plan sampling, data collection and analysis, and justify every choice.
5. Deal with ethics: approval, consent, privacy and data handling.

Common Methodology Mistakes

• Picking a method first and bending the question to fit it.
• Claiming cause and effect on the basis of a survey or correlational design.
• Samples that are too small or unjustified.
• Using questionnaires that were not validated or piloted.
• Leaving limitations unstated; see reasons for rejection.

Methodology in a JMVRA Paper

JMVRA reviewers judge whether your methodology is sound and fits the question. Set it out clearly in the methods section, add ethics statements where relevant, and follow the publication guidelines and journal template. Also see research paper format. Short, specific descriptions are easier for reviewers to evaluate than general statements.

Practical Tips for Defending Your Methodology Choices

A methodology section convinces readers only when every choice is justified by the research problem. These habits help you build a design that reviewers can follow and trust from the first reading.

• Start from the question, not the tool. Write your research question in a single sentence and ask what kind of evidence would truly answer it. Choose the approach only after that, so the design never looks like a favourite technique searching for a problem.
• Keep a decision diary. Note each design choice as you make it, together with the reason and the alternative you rejected. Later, this diary turns into a clear justification paragraph that saves you from vague, last-minute explanations.
• Test your instruments early. Try your questionnaire, interview guide or measurement procedure on a small group before the main study. Pilot feedback exposes confusing wording, impossible timings and missing options while they are still cheap to fix.
• Describe steps another person could repeat. Explain who or what was studied, how they were selected, what was done and in which order. If a capable stranger could not rerun your procedure from the text, add the missing detail.
• State limitations before reviewers do. Admit honestly where your sample, setting or method restricts what can be claimed. A calm, specific limitations note shows judgement and usually earns more trust than silence on weak points.

Let the research question drive every methodological choice, and record your reasons while you work so the written section reads as deliberate rather than accidental.

Questions Researchers Often Ask

In Summary

Methodology is the backbone of a research paper. Let your research question determine the approach, select a design capable of answering it, justify sampling, data collection and analysis, deal with quality and ethics, and be honest about your limitations. A clear and justified methodology makes each later section more persuasive.
