Question

1. what is one limitation of systematic sampling?

a. it requires creating subgroups within the population
b. it may produce biased results if patterns exist in the population
c. it is too slow for large populations
d. it cannot be used for geographically dispersed groups

Explanation:

Systematic sampling selects elements at regular intervals from an ordered population. If there are hidden patterns in the population that align with the sampling interval, it can lead to biased results. For example, if a factory produces items in a cycle where every 10th item has a defect and the sampling interval is 10, the sample will be biased.

Answer:

B. It may produce biased results if patterns exist in the population
