Research Design and Methodology

• Quantitative research involves the collection and analysis of numerical data
  • Employs statistical techniques to test hypotheses and draw conclusions
  • Suitable for research questions that require measurement, comparison, and generalization
• Qualitative research involves the collection and analysis of non-numerical data (interviews, observations)
  • Focuses on understanding the subjective experiences, perceptions, and meanings of participants
  • Suitable for research questions that require in-depth exploration and contextual understanding
• Mixed methods research combines both quantitative and qualitative approaches
  • Leverages the strengths of both approaches to provide a more comprehensive understanding of the research problem
  • Suitable for research questions that require triangulation and complementary insights
• Sampling techniques involve the selection of a subset of the population for the study
  • Probability sampling (random sampling) ensures that each member of the population has an equal chance of being selected
  • Non-probability sampling (purposive sampling) involves the deliberate selection of participants based on specific criteria
• Validity and reliability considerations ensure the quality and rigor of the research design
  • Internal validity refers to the extent to which the research design allows for causal inferences
  • External validity refers to the generalizability of the research findings to other contexts or populations
  • Reliability ensures the consistency and reproducibility of the research instruments and procedures
