Explanation:
Detailed explanation-1: -A stratified sample is one that ensures that subgroups (strata) of a given population are each adequately represented within the whole sample population of a research study. For example, one might divide a sample of adults into subgroups by age, like 18–29, 30–39, 40–49, 50–59, and 60 and above.
Detailed explanation-2: -Difference between stratified sampling and systematic sampling? In systematic sampling, the list of elements is “counted off". That is, every kth element is taken. Stratified sampling also divides the population into groups called strata.
