What are the Types of Research Methodology?
Research methodology encompasses various strategies and approaches for gathering, analysing, and interpreting data. The main types of research methodologies can be broadly categorized into two groups: qualitative and quantitative. Each has distinct characteristics, methods, and applications. Here's an overview:
- Quantitative Research: Quantitative research involves collecting and analysing numerical data to identify patterns, relationships, or trends. It is often used to test hypotheses and make predictions.
- Qualitative Research: Qualitative research involves collecting and analyzing non-numerical data to understand concepts, opinions, or experiences. It focuses on depth rather than breadth.
- Mixed-Methods Research: Mixed-methods research combines both qualitative and quantitative approaches to provide a more comprehensive understanding of a research problem.
Steps in Research Methodology

6. Data Collection Methods
- Surveys/Questionnaires: These are common in quantitative research for gathering large data sets.
- Interviews/Focus Groups: Useful in qualitative research for in-depth understanding.
- Observations: Directly watch and record behaviours or events.
- Experiments: Manipulate variables to observe effects.
7. Data Analysis Techniques
- Quantitative Analysis: Use statistical tools to interpret numerical data (e.g., SPSS, Excel).
- Qualitative Analysis: Employ methods like thematic analysis or coding to analyze text or audio data.
8. Interpreting Results
- Compare with Hypotheses: See if the data supports your initial predictions or answers your research questions.
- Draw Conclusions: Summarize the main findings and their implications.
9. Reporting and Presentation
- Structure the Report: Include sections like introduction, literature review, methodology, results, discussion, and conclusion.
- Visual Aids: Use charts, graphs, and tables to present data clearly.
10. Ethical Considerations
- Informed Consent: Ensure participants are aware of the study's purpose and consent to participate.
- Confidentiality: Protect the privacy of participants and handle data responsibly.

Example Structure
Here's a simplified example to illustrate how these elements might be structured:
Introduction: "The aim of this study is to explore the impact of social media on adolescent self-esteem. To achieve this, a mixed-methods approach was employed, combining quantitative surveys with qualitative interviews."
Research Design: "This study utilizes a sequential explanatory design, starting with a quantitative survey to gather broad data, followed by qualitative interviews to gain deeper insights."
Participants/Sample: "The target population is adolescents aged 13-18 years in urban schools. A sample of 200 students was selected using stratified random sampling to ensure representation across different age groups and genders."
Data Collection Methods: "Data were collected using a validated self-esteem questionnaire and semi-structured interview guides. Surveys were administered in classrooms, and interviews were conducted in a private room at the school."
Data Analysis: "Quantitative data were analyzed using descriptive and inferential statistics with SPSS. Qualitative data were coded and thematically analyzed using NVivo. Reliability was assessed through Cronbach's alpha, and validity was checked through expert review."
Ethical Considerations: "Ethical approval was obtained from the institutional review board. Written informed consent was obtained from all participants and their guardians. Data confidentiality was maintained by anonymizing responses and securely storing data."
Limitations: "One limitation is the reliance on self-reported data, which may be subject to social desirability bias. Efforts were made to minimize this by assuring participants of their anonymity."
By following these guidelines and structuring your methodology in a clear, detailed, and logical manner, you will create a robust foundation for your research that others can understand, evaluate, and replicate.
