3) Stratification variable

Explanation:
  1. In Stratified Sampling, the population is divided into subgroups (strata) based on a specific characteristic, and then random samples are taken from each stratum.
  2. In this case, gender is the variable used to divide the population into strata (males and females).
  3. The variable used for this division is called the stratification variable because it is used to create homogeneous groups before sampling.
Thus, gender is the stratification variable in this scenario.
