Question

A survey related to presidential favorability was administered to members of the same party as the president. The results of the survey showed 85% fallibility. Another national survey was administered to members of both parties. The result of this survey showed 45% favorability. This is a classic example of an error in which phase of inferential statistics?

a) Sampling error
b) Type I error
c) Type II error
d) Non-sampling error

Answer 1

The error in this situation is a sampling error, specifically related to the sample used in the survey.

Step-by-step explanation:

This is an example of a) Sampling error. Sampling error occurs when the sample used in a study is not representative of the entire population. In this case, the first survey was administered only to members of the same party as the president, which may not accurately reflect the opinions of the entire population. The second survey, which included members of both parties, is more likely to provide a more accurate representation.
