How to Ensure the Representativeness of the Study Population?

The representativeness of the study population is critical for generalizing the findings to a larger group. To ensure representativeness:

- Random Sampling: Use random sampling methods to select participants, which helps in obtaining a sample that closely mirrors the target population.
- Stratified Sampling: This involves dividing the population into subgroups (strata) and sampling within each subgroup. It ensures that all segments of the population are adequately represented.
- Inclusion and Exclusion Criteria: Clearly define these criteria to ensure that the study includes participants who are relevant to the research question and excludes those who may skew the results.
