Stratified random sampling is used to make general statements about specific portions of the population that have been sampled. It is a useful technique when the population of interest can be divided into distinct subgroups, or strata, and the researcher wants to ensure that each stratum is represented in the sample in proportion to its size in the population. This allows the researcher to draw conclusions about each subgroup of the population separately and make generalizations about the population as a whole.
