Answer: proportionate stratified random sampling

Explanation: Porportionate stratified random sampling is a sampling technique in which subgroups also called stratums of a given sample or population are stratified, that is adequately represented within the entire population. In this sampling technique, the assigned size of each stratum is proportionate to the population size of the strata with respect to the size of the entire population. Hence, employs a uniform sampling fraction in deciding sample size across each stratum.

In the scenario above, population size is 40% male and 60% female, sample size is 20 male and 30 female meaning that the same sample fraction was adopted across both stratum with the sample size proportionate to the population size of the strata.
