How to Choose Dissertation Methodology

Choosing the right methodology for your dissertation is crucial because it shapes how you collect, analyze, and interpret data. Your methodology will depend on the nature of your research question, your discipline, and the type of data you need to collect. Here’s how to approach selecting the best methodology:

1. Understand Your Research Question

  • Your methodology should align with the research question you are trying to answer. Ask yourself:

    • Do I need to explore individual experiences and perceptions, or am I testing a hypothesis?

    • Am I interested in understanding a social process, or am I trying to measure relationships between variables?

  • Example: If your research question is focused on understanding experiences or meanings (e.g., “How do people perceive the effects of social media on relationships?”), qualitative methods are likely appropriate. If you’re examining a relationship between two variables (e.g., “Does social media use correlate with decreased social interaction?”), quantitative methods may be better suited.

2. Consider Your Discipline

  • Different academic disciplines favor different research methodologies:

    • Social Sciences and Humanities often use qualitative methods (e.g., interviews, case studies, ethnography) to understand human behavior and social phenomena.

    • Natural Sciences and Engineering typically favor quantitative methods (e.g., experiments, surveys, statistical analyses) for hypothesis testing and data measurement.

    • Mixed Methods can be used in interdisciplinary fields or when a combination of both qualitative and quantitative approaches is needed.

3. Determine the Type of Data

  • Qualitative Data: If you are exploring complex phenomena, experiences, or social processes where meaning is important, qualitative methods may be the best choice. These methods deal with non-numerical data such as words, images, and texts.

  • Quantitative Data: If you are interested in measuring something, testing a hypothesis, or establishing patterns through numerical data, quantitative methods are more appropriate.

  • Mixed Methods: If your research requires both types of data, you can use a mixed-methods approach to gain a comprehensive understanding.

4. Evaluate Available Resources and Time

  • Data Collection Methods: Consider how you can realistically collect the data. For qualitative research, data collection methods may include interviews, focus groups, or observations, which are time-intensive. For quantitative research, surveys or experiments may be more efficient but still require careful planning.

  • Data Analysis: Qualitative data analysis involves coding and theme identification, while quantitative analysis often requires statistical tools. Consider your comfort level with these analysis techniques and available resources.

5. Ethical Considerations

  • Some methodologies require ethical clearance, particularly qualitative research that involves human participants. Be sure to choose a methodology that you can ethically and responsibly implement.
