Question

a mega - discount chain store just opened a new clothing store in town emphasizing mainly womens clothing. before opening, management had to decide whether to only carry either mens, womens, boys, girls, or infants clothing. after performing representative sampling of potential customers from each of these groups, it was decided to carry only womens clothing. identify the type of sampling used in this example. a. multistage sampling b. stratified sampling c. systematic sampling d. cluster sampling

Explanation:

Stratified sampling involves dividing the population into distinct subgroups (strata) based on characteristics (here, customer groups: men’s, women’s, boys’, girls’, infants’ clothing customers) and then sampling from each stratum. The management sampled potential customers from each of these groups (strata) to make a decision, which fits stratified sampling. Multistage sampling involves multiple stages of sampling, systematic sampling uses a fixed interval, and cluster sampling samples entire clusters (not applicable here as groups are strata, not clusters).

Answer:

B. Stratified sampling
