The process of stratified sampling involves several key steps:
1. Identify Strata: The population is divided into mutually exclusive subgroups based on relevant characteristics. 2. Determine Sample Size: Decide how many individuals will be sampled from each stratum. This can be proportional (same fraction from each stratum) or equal (same number from each stratum). 3. Random Sampling: Within each stratum, individuals are randomly selected to ensure the sample is representative.
