Question

a population is divided into two groups: males and females. 10 males are randomly chosen from the first group and 10 females are randomly chosen from the second group. what type of sampling method is being used?

• stratified random sample
• random cluster sample
• simple random sample (srs)
• none of the above

Explanation:

Stratified random sampling involves dividing the population into distinct subgroups (strata) and then taking a random sample from each stratum. Here, the population is divided into males and females (strata), and 10 are sampled from each. Cluster sampling would involve sampling entire clusters, and simple random sampling is from the whole population without stratification. So the correct method is Stratified Random Sample.

Answer:

A. Stratified Random Sample
