Stratified sampling is a method of sampling that involves dividing a population into distinct subgroups, or strata, based on specific characteristics, and then randomly selecting samples from each stratum. This technique ensures that each subgroup is adequately represented in the sample, which can lead to more accurate and reliable results in statistical analysis and decision making. By recognizing the diversity within the population, stratified sampling enhances the precision of estimates and helps avoid biases that can arise from simple random sampling methods.
