- Cohort Studies: These follow a group of people who share a common characteristic or experience within a defined period .
-
Advantages:
- Provides a comprehensive summary of the data, which can be used to identify patterns and trends .
- Useful for generating hypotheses that can be tested in future research .
-
Limitations:
- Cannot determine cause-and-effect relationships .
- May be subject to biases if the sample is not representative of the population .
Conclusion
Descriptive research design in quantitative research is a valuable method for summarizing and describing the characteristics of a population or phenomenon.
