F
No questioning or communication with people is needed in observation.

Answer to Question 2

The response rate is the number of questionnaires returned or completed divided by the number of eligible people who were asked to participate in the survey. Typically, the number in the denominator is adjusted for faulty addresses and similar problems that reduce the number of eligible participants.

Below are ways to increase response rates for mail surveys:
(1) Include a cover letter.
(2) Offer monetary incentive or premiums.
(3) Include interesting questions.
(4) Conduct follow-ups, which may include a duplicate questionnaire or merely be a reminder to return the survey; use codes to key questionnaires.
(5) Notify respondents in advance.
(6) Keep survey sponsor anonymous.
(7) Other techniques include types of envelopes, stamps, and color of questionnaire paper.
