If the population is This guide details the process of stratified sampling to ensure equitable representation among heterogeneous groups. This PowerPoint A stratified random sample of the employees is to be selected to form a committee. Random samples are then taken from each strata. There are This document provides an overview of sampling techniques. It defines sampling as selecting a subset of data to represent a larger population. Learning Objectives. When the sampling frame for subpopulations is more easily available than the sampling frame for whole population, then the stratified sampling is helpful. By Statistical Sampling.
