1. What is the purpose of research design in a study?
● Answer: The purpose of research design is to provide a structured plan for how to
conduct the study. It helps in determining the methodology, data collection techniques,
and analysis methods. A good research design ensures that the study is valid, reliable,
and can accurately answer the research questions.
2. What are the main types of research designs?
● Answer: The main types of research designs include:
○ Descriptive: Focuses on describing characteristics or functions.
○ Correlational: Examines the relationships between variables.
○ Experimental: Tests cause-and-effect relationships through controlled
experiments.
○ Quasi-Experimental: Similar to experimental but lacks random assignment.
○ Case Study: Provides a detailed analysis of a single case or a few cases.
○ Cross-Sectional: Studies variables at one point in time.
○ Longitudinal: Studies variables over an extended period.
3. How do you determine the sample size for a study?
● Answer: Sample size is determined based on factors such as the study’s objectives, the
population size, the desired confidence level, and the acceptable margin of error.
Statistical formulas and software tools can help calculate the required sample size to
ensure that the results are statistically significant.
4. What is the difference between qualitative and quantitative research
methods?
● Answer:
