Stratified sampling is a sampling method in scientific research that involves ensuring your sample group has fair representation of sub groups (strata) of a population youโre studying. Stratification is particularly more effective when there are extreme values in the population which can be segregate to from different strata: for example, the adult population may be divided into higher income, lower and unemployed sections. In stratified sampling, researchers divide subjects into subgroups called strata based on characteristics that they share.

In stratified sampling, researchers divide subjects into subgroups called strata based on characteristics that they share. The stratified random sampling tool in ncss can be used to quickly generate k independent stratified random samples from a dataset, where each random sample has n items divided among h strata. Explore stratified sampling examples, differentiating it from cluster and random samples. understand stratified random sampling's benefits for precise samples. Here, we present examples of how to split data using this generalized stratified sampling repository. to begin, first acquire the example data spreadsheet here (you will need to be signed into a data.midrc.org account to access the example data). In this section we shall also present some examples of such populations which are either available in the stratified form or stratified by the sampler himself herself using certain characteristic(s) of the population as per the objectives of the survey.
