Stratified sampling is used when the population is believed to have a skewed distribution for one or more of its distinguishing factors. It involves dividing the population into strata or groups that are homogeneous within themselves but heterogeneous between each other based on certain characteristics, ensuring that each subgroup is adequately represented in the sample. This method helps in obtaining a more representative sample by minimizing sampling bias, especially in skewed distributions.
