What Is Research Methodology?
Chapter 3, or the Research Methodology, is your study’s blueprint. It’s not about the results or the interpretation, it’s about the method you used to get them. You walk readers through every major decision: where your research took place, who your participants were, how you collected data, and how you made sure the study was ethical and valid.
This chapter is crucial for building credibility and showing that your research process was intentional, logical, and replicable.
Structure of Chapter 3 in Research
A well-written Chapter 3 has a clear structure. Each section builds on the last, giving readers a full picture of how you carried out your research.
What to Include in Chapter 3
- Research Design: The overall strategy or blueprint of your research qualitative, quantitative, or mixed methods.
- Research Locale and Context: Where the study was conducted and relevant setting details that affect your data.
- Population and Sampling: Who your participants are, how you selected them, and how many were involved.
- Research Instruments: The tools used to collect data (e.g., surveys, interview guides, tests).
- Data Gathering Procedure: Step-by-step process of how data was collected from planning to implementation.
- Data Analysis Plan: How raw data was processed, interpreted, and turned into findings.
- Ethical Considerations: Actions taken to protect participants and uphold ethical research standards.
- Summary of the Chapter: Brief recap and transition to Chapter 4, where results are presented.
