Abstract: |
Stratified sampling is one of the most widely used sampling methods.
Its defining characteristic—and at the same time its main advantage—is that it typically produces lower standard errors for the estimators compared to other sampling methods. During the design stage of the survey, the population is divided into strata. Strata are subsets of the population that meet specific criteria or share certain characteristics. Then, an independent sample is drawn from each stratum, and the final sample consists of the collection of all the individual samples from the different strata. In this way, the overall sample selected from the population includes representatives from each distinct stratum. If the strata are defined in such a way that they correspond to meaningful or distinct subgroups of the population, the sample obtained through stratified sampling will be representative. Stratified sampling can be used either on its own or in combination with other sampling methods as part of a more complex sampling design.
