A. In stratified random sampling, a larger population is divided into distinct subgroups, or strata, that share similar characteristics to study their appreciable differences. By dividing the population into strata that share similar characteristics, researchers can draw random samples from each group in proportion to their sizes in the overall population. This ensures that every subgroup is adequately represented, enhancing the accuracy and reliability of the results.
