Choosing the right research methodology can feel like one of the biggest decisions of your entire master’s journey. And honestly? It is. Your methodology affects the kind of data you collect, the conclusions you can make, and ultimately how strong your thesis becomes.
Whether you’re writing your first methodology chapter or trying to understand the difference between methods and methodology, this guide reveals the types of research methodology and breaks things down in a clear, friendly, and practical way.
Ready? Then, let’s get to it.
What Is Research Methodology? (And Why Is It Important)
Research methodology is simply the overall strategy you use to answer your research questions.
If your thesis were a house, the methodology would be the architectural blueprint, your plan, while your methods (interviews, surveys, experiments) are the tools you use to build it.
“A strong methodology is what separates a good study from a great one, because it shows you didn’t just gather data; you gathered the right data.”
A clear methodology helps you:
- Stay focused
- Work efficiently
- Justify your research decisions
- Produce credible, repeatable findings
The 4 Main Types of Research Methodology
Below are the most commonly used types of research methodology in master’s theses. Each one is powerful in its own way. Your job is simply to choose the one that fits your research goals.
1. Quantitative Research Methodology
This approach involves numbers, statistics, and measurable variables. If you want to test relationships, measure outcomes, or generalize findings, quantitative design is your best friend.
When to Use It
Use this if your study involves:
- Hypothesis testing
- Experiments
- Surveys with structured questions
- Numerical measurement
Example
A study measuring the impact of study hours on GPA.
Common Quantitative Designs
- Experimental
- Quasi-experimental
- Correlational
- Survey-based
Why Students Choose It
It’s systematic, objective, and often easier to defend during a thesis defense because the data “speaks for itself.”
2. Qualitative Research Methodology
Qualitative research dives into experiences, perceptions, emotions, patterns, and meanings. Instead of numbers, it relies on rich, descriptive data.
When to Use It
Choose qualitative methods if your research involves:
- Understanding human behavior
- Exploring lived experiences
- Interpreting meaning
- Studying environments and contexts
Examples
- A study on how first-generation students experience academic stress
- An exploration of teachers’ perceptions of digital learning tools
Common Qualitative Designs
- Phenomenology
- Case Study
- Ethnography
- Narrative Research
- Grounded Theory
Why Students Choose It
It allows for depth, nuance, and a more human story. Many education, social sciences, and humanities students prefer this.
3. Mixed Methods Research
Mixed methods research blends quantitative and qualitative research. If one data source isn’t enough to fully answer your question, this approach gives you the best of both worlds.
When to Use It
Choose mixed methods if:
- Your research question requires both numbers and stories
- You need to validate one form of data with another
- You want deeper insights
Common Mixed Methods Designs
- Convergent (collect both types at once)
- Explanatory sequential (quant → qual)
- Exploratory sequential (qual → quant)
Example
study that surveys teachers on digital classrooms, then interviews selected teachers for deeper insights.

4. Theoretical / Conceptual Methodology
This approach focuses on building, analyzing, or refining theories, rather than collecting data from participants.
When to Use It
- Your field is theoretical (e.g., philosophy, mathematics, policy analysis)
- You’re synthesizing existing literature to propose a new model
- Your goal is conceptual—not empirical—contribution
Example
A thesis proposing a new framework for understanding online learning motivation.

Comparison Table: Types of Research Methodology
| Methodology Type | Data Type | Typical Tools | Strengths | Best For |
|---|---|---|---|---|
| Quantitative | Numbers | Surveys, experiments | Precise, generalizable | Measuring relationships, testing hypotheses |
| Qualitative | Text, audio, visuals | Interviews, observations | Deep insights, flexible | Exploring experiences, meanings |
| Mixed Methods | Both | Surveys + interviews | Holistic, balanced | Complex research questions |
| Theoretical | Concepts | Models, frameworks | Strong conceptual value | Theory-building |
How to Choose the Best Research Methodology for Your Thesis
Choosing among the types of research methodology doesn’t have to be stressful. Start with your research questions.
Ask yourself:
What type of data answers my question?
If you need numbers → quantitative
If you need experiences → qualitative
If you need both → mixed methods
What is feasible for me?
Consider:
- Time
- Access to participants
- Skills (e.g., statistical skills, interview skills)
What aligns with my field?
Different disciplines have norms—business often prefers quantitative; humanities often prefer qualitative.

How to Write Your Methodology Chapter (Simple Structure)
A strong methodology chapter includes:
1. Research Design
Explain whether your study is quantitative, qualitative, mixed methods, or theoretical.
2. Participants or Data Sources
Who or what are you studying?
3. Data Collection Methods
Examples:
- Interviews
- Surveys
- Focus groups
- Experiments
- Secondary data
4. Instruments
Questionnaires, interview guides, observation checklists, etc.
5. Data Analysis
- Thematic analysis for qualitative
- Statistical tests for quantitative
- Integration approach for mixed methods
6. Validity/Reliability (or Trustworthiness)
Show the rigor behind your choices.
7. Ethical Considerations
Confidentiality, anonymity, informed consent, etc.
Common Mistakes Students Make When Choosing a Methodology
Here are pitfalls to avoid:
Choosing a method because it “seems easy”
A weak methodology leads to a weak thesis.
Not aligning methodology with research questions
This is a major thesis defense red flag.
Mixing methods without justification
Mixed methods isn’t “do everything”, it’s strategic.
Using tools you don’t understand
Learn basics of statistical analysis or qualitative coding before collecting data.

Conclusion
Understanding the types of research methodology is one of the most important steps you can take toward writing a high-quality thesis. When your methodology aligns with your research questions, your findings become clearer and stronger.
Take your time, explore your options, and choose the approach that helps you tell the story your research truly deserves.
