Question

a manager wants to gauge employee satisfaction at a company. she hands out a survey questionnaire to everyone in the human resources department who were hired in the past two years. the employees must respond to the questionnaire within five days.
what type of bias are the survey results at risk for?
a. the survey results are most at risk for undercoverage.
b. the survey results are at risk for nonresponse bias and undercoverage.
c. the survey results are not at risk for any bias.
d. the survey results are most at risk for nonresponse bias.

Explanation:

1. Undercoverage bias: This occurs when some groups in the target population are excluded from the sample. The manager only surveys HR department employees hired in the last two years, excluding all other departments and longer-tenured HR employees, so undercoverage is present.
2. Nonresponse bias: This happens when selected individuals do not respond to the survey. The requirement to respond in five days means some employees may not submit the survey, leading to nonresponse bias.

Answer:

B. The survey results are at risk for nonresponse bias and undercoverage.
