Question

at the beginning of a call to the cable company, a message tells customers, after you finish talking to our customer service representative, you will be asked to take a five - question survey about the level of service you received. it would be appreciated if you could please stay on the line to answer the survey questions. what type of sampling is the cable company using?

• systematic random sampling
• voluntary sampling
• cluster sampling
• convenience sampling

Explanation:

To determine the sampling type, we analyze each option:

• Systematic random sampling: Involves selecting every nth individual, which is not the case here.
• Voluntary sampling: Participants choose to respond (volunteer). The cable company asks customers to stay on the line and answer the survey, meaning customers can choose to participate (volunteer) or not. This matches voluntary sampling.
• Cluster sampling: Divides the population into clusters and samples entire clusters, which is not applicable here.
• Convenience sampling: Uses easily accessible individuals, but here it's about customer choice to participate, not just accessibility.

Answer:

B. voluntary sampling
