Question 3.102

3.102 Can you remember how many?

An opinion poll calls 2200 randomly chosen residential telephone numbers, and then asks to speak with an adult member of the household. The interviewer asks, “How many movies have you watched in a movie theater in the past 12 months?”

  1. What population do you think the poll has in mind?
  2. In all, 1435 people respond. What is the rate (percent) of nonresponse?
  3. For the question asked, what source of response error is likely present?
  4. Write a variation on this question that would reduce the associated response error.
