Answer 1

Answer:

Stratified random sampling.

Step-by-step explanation:

In Statistics, Stratified random sampling can be defined as a method of sampling that involves dividing a population into smaller groups known as strata.

In stratified random sampling, the strata are formed based on member's shared characteristics (e.g female or male, occupation, education) or attribute (e.g black or white).
