Quizplus · Accepted Answer

Oversampling is commonly used in Stratified random sampling. In this technique, the sample is divided into strata or subgroups based on certain characteristics, and then within each stratum, an oversampling technique is used to increase the sample size to ensure a sufficient number of observations for the subgroups of interest. This results in a more precise estimation of characteristics of the population within each subgroup.
