Question

question 4 of 10 the student council at mountain view high school plans to conduct a survey to determine the student body’s opinion of the new lunch menu. which of the following sampling methods would be most likely to result in self-selection bias?

a. obtaining an alphabetical list of all students and surveying every 10th student

b. handing out a questionnaire to seniors only

c. setting up a booth in the lunchroom where students can give their thoughts

d. handing out a questionnaire to students leaving campus at lunchtime

Explanation:

• Option A: Systematic sampling (every 10th student) is less likely to have self - selection bias as it's a structured sampling method.
• Option B: Sampling only seniors is a form of convenience sampling based on grade, not self - selection (students don't choose to be surveyed, they are in a specific group).
• Option C: When a booth is set up in the lunchroom and students can choose to give their thoughts, students self - select whether to participate. This means that those with stronger opinions (either positive or negative) are more likely to participate, leading to self - selection bias.
• Option D: Handing out questionnaires to students leaving campus at lunchtime is a convenience sample based on a specific time - related group, not self - selection (students are in a group and given the questionnaire, they don't choose to be in the survey group in the same way as option C).

Answer:

C. Setting up a booth in the lunchroom where students can give their thoughts
