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:

Analyze the scenario

Using the Voluntary Response Sampling knowledge point

The cable company asks customers to choose whether or not they want to stay on the line to answer a survey. Because the participants themselves decide whether to be part of the sample, this is a self-selected group.

Evaluate the options

Using the Voluntary Response Sampling knowledge point

• systematic random sampling: Involves selecting members at a regular interval (e.g., every 10th caller). This is not the case here.
• voluntary sampling: Occurs when individuals choose to participate in the survey on their own accord. This matches the scenario perfectly.
• cluster sampling: Involves dividing the population into groups (clusters) and selecting entire clusters at random. This does not apply.
• convenience sampling: Involves choosing individuals who are easiest to reach. While convenient for the company, the defining characteristic here is that the customer must actively choose to stay on the line (volunteer).

Answer:

• systematic random sampling
• voluntary sampling (Correct answer)
• cluster sampling
• convenience sampling
