What is stratified sampling?

• Stratified sampling is a sampling technique where the population is divided into random subgroups called strata, and then a random sample is taken from each stratum in proportion to the population size of that stratum.

• Stratified sampling is a sampling technique where the population is divided into non-overlapping subgroups called strata, and then a random sample is taken from each stratum in proportion to the population size of that stratum.
