Selecting a study population involves several steps:
Define the Research Question: The first step is to clearly define the research question. This helps in identifying the characteristics of the study population. Inclusion and Exclusion Criteria: Researchers set inclusion and exclusion criteria to determine who will be part of the study. These criteria are based on factors such as age, gender, health status, and other relevant characteristics. Sampling Methods: Various sampling methods can be used to select the study population, including random sampling, stratified sampling, and cluster sampling. The choice of method depends on the study design and objectives.
