Name the categories (stratum) in the population. Stratified sampling is a method that divides the population into smaller subgroups known as strata based on shared characteristics. Find standard error, margin of error, confidence interval. This method is particularly useful when certain strata are underrepresented An example of Stratified Sampling. This video by Arya Anjum explains the concept, formula, Divide your sample into strata depending on the relevant characteristic (s).
