Question

1. how can non - response bias affect the outcome of a survey?

a. by skewing the results toward the opinions of those who respond
b. by making the survey easier to analyze
c. by making the survey shorter
d. by increasing the response rate

Explanation:

Non - response bias occurs when those who respond to a survey have different opinions or characteristics than those who do not respond. This means that the survey results will be skewed towards the opinions of the respondents. Options b, c, and d are incorrect. Making the survey easier to analyze or shorter is not related to non - response bias. Non - response bias actually decreases the effective response rate (since some people don't respond), not increases it.

Answer:

A. By skewing the results toward the opinions of those who respond
