Question

Quizplus · Accepted Answer

Stratified sampling is useful when the population is heterogeneous or skewed, as it allows for more accurate representation of all subgroups within the population. By dividing the population into strata, the variability within each stratum is reduced, leading to more precise estimates of the population parameters. Therefore, stratified sampling can be a powerful tool for obtaining a representative sample in such situations.
