Stratified sampling involves dividing the population into homogenous subgroups or strata and then selecting a random sample from each stratum. In this example, potential customers were divided into subgroups based on their sex and a random sample was taken from each group. This allowed the management to make an informed decision about what type of clothing to carry in their store.
