Question

a researcher interviews students who drive to school every day and asks them what their favorite food is. which of these groups would be most affected by undercoverage?

• students who drive to school every day
• students who have unpopular choices for favorite food
• students who are younger than 16 and cannot legally drive
• students who do not have a strong opinion about their favorite food

Explanation:

Undercoverage occurs when a sampling frame excludes part of the population. The researcher samples only students who drive to school daily. Students younger than 16 (who can't legally drive) are excluded from the sampling frame, so their group is most affected by undercoverage. The other groups either are part of the sampled group (students who drive daily) or relate to food preferences (not excluded by the sampling method).

Answer:

C. Students who are younger than 16 and cannot legally drive
