Key Concepts

Stratified Sampling

Stratified sampling is a method where the overall population is divided into distinct subgroups, or strata, based on shared characteristics, and samples are then chosen from each subgroup. This approach ensures that each subgroup is adequately represented in the sample, even though the selection process is not random. The goal is to achieve a balanced representation across different segments of the population, which can lead to more reliable insights about the population as a whole.

Proportional Sampling

Proportional sampling is a technique wherein each subgroup, or stratum, contributes to the overall sample in proportion to its size relative to the entire population. This ensures that larger groups are given more weight in the sample than smaller ones, providing a sample that mirrors the actual distribution of the population. This method is particularly useful when the objective is to reflect the true population ratios, ensuring that the findings are representative of the overall demographics.
