Explanations:
Dr. Chen's results indicate that individuals overestimate the amount of money they give to their churches and private schools. This overestimation is likely due to social desirability bias, where people tend to report behaviors that are perceived as socially desirable, such as charitable giving, in a more positive light than is actually true.
Option Analysis:
Option A:
Over-representation bias refers to a situation where certain groups are overrepresented in a sample, which is not the issue here. The problem is with the individuals' reporting behavior.
Option B:
Social desirability bias is the correct answer as it explains why individuals might overestimate their charitable contributions to appear more generous.
Option C:
Poor random sampling would affect the representativeness of the sample, not the accuracy of individual responses.
