Question

A.

1
client to survey.

B.
The company should survey every
5
th
client that makes an appointment.

C.
The company should choose the first
50
clients that volunteer to take the survey.

D.
The company should have a computer randomly generate a list of
200
clients to survey.

Answer 1

To ensure a representative sample of clients and to enhance the quality of the survey results, the company should select options that promote randomization and representation. The best choices from the options provided are:

B. The company should survey every 5th client that makes an appointment.

This method uses systematic sampling and, while it may not be fully random, it can provide a good representation of clients, especially if appointments are made throughout a wide range of times and conditions.

D. The company should have a computer randomly generate a list of 200 clients to survey.

This method is the most effective for random sampling, allowing each client an equal chance of being selected, which can help minimize bias and ensure the sample reflects the broader client base.

Options A and C are not ideal as they introduce bias (personal recommendations may not represent the overall client population, and volunteer sampling can result in self-selection bias).
