b. A group of 100 married men are asked if they have ever cheated on their spouse.

c. Potential voters are asked “Do you plan to vote for Candidate A, even though all recent polls show he will lose the election?”

Answer 1

(a)

Potential source of bias:

Undercoverage bias

EXPLANATION:
Since the survey is with only Facebook users, those people who are not accessing Facebook are not able to participate in the survey about their brand of coffee.

(b)

Potential source of bias:

Nonresponse - Social desirability bias:

Individuals chosen for the sample are unwilling to participate in the survey. Here, the survey question is whether they have ever cheated on their spouse . A married man will never agree that he has cheated his spouse because of social desirability.and also because the survey results are not confidential

Potential source of bias:

Leading question bias:

The wording of the question is loaded in a way to unduly favor one response over another. Here, the wordings, " even though all recent polls show he will lose the election" unduly favors against Candidate A.
