Question

Suppose a politician sent out 860 surveys. Which of these numbers of

surveys being returned would prevent nonresponse bias?

A. 6

B. 8

C. 860

D. 86

Answer 1

860

Explanation:

A non-response bias would mean that there are some non-response surveys, which will create a bias in the survey results. Because the survey didn't include information from those who are not responded.

If there will be 860 surveys back, this would prevent non-response bias
