What distinguishes "Prevent Ballot Box Stuffing" and "Randomize Responses"?

The correct choice highlights two distinct functionalities related to survey integrity and response collection methods. "Prevent Ballot Box Stuffing" specifically refers to mechanisms employed to ensure that each participant can only submit one response, effectively limiting responses to unique individuals. This is crucial in maintaining the validity of the survey data, as multiple entries from the same person can skew results.

On the other hand, "Randomize Responses" is a technique that involves varying the order of answer choices presented to participants. This helps eliminate bias that may arise from the positioning of response options, ensuring that no particular choice is systematically favored due to its placement in the list.

The distinction is important as each function serves a different purpose in survey administration—one focuses on controlling the quality of participant data by preventing duplicate submissions, while the other enhances the randomness and fairness of the responses collected.
