Question

in a study, the sample is chosen by dividing the population by gender, and choosing 30 people of each gender assuming an equal number of men and women in the population. what is the sampling method? ○ systematic ○ convenience ○ cluster ○ stratified ○ simple random

Explanation:

• Systematic: Involves selecting every nth element, not applicable here as gender groups are used.
• Convenience: Uses easily accessible subjects, not the case here.
• Cluster: Divides into clusters and samples entire clusters; here, samples from each gender (strata), not clusters.
• Stratified: Divides population into strata (gender here) and samples from each stratum (30 from each gender), matching the description.
• Simple Random: Random selection from entire population, not dividing into groups first.

Answer:

D. Stratified
