Question

1. to determine how satisfied patients are with the services they have received, a hospital contacts a sample of 1,524 patients via email. the patients are presented with a survey to complete, and 183 patients complete and return the survey. this illustrates something called

a. a nonsampling error because some patients refused to cooperate by completing the survey.
b. an undercoverage error because the hospital missed an opportunity to survey all patients.
c. a standard error because the number of patients who completed the survey will have an impact on variability.
d. a sampling error because not all patients were contacted by the hospital.
e. a margin of error because the sample responses will only approximate what is going on in the population.

Explanation:

Nonsampling errors occur due to factors other than the sampling - process, such as non - response. Here, some patients refused to cooperate (non - response), which is a form of nonsampling error. Undercoverage is about not including parts of the population in the sampling frame. Standard error is related to sampling variability. Sampling error is due to the fact that we are sampling instead of surveying the whole population. Margin of error is related to the precision of estimates from a sample.

Answer:

A. a nonsampling error because some patients refused to cooperate by completing the survey.
