Question:

a. A survey researcher reports that “205 usable questionnaires out of 942 questionnaires delivered in our mail survey converts to a 21.7 percent response rate:” What are the subtle implications of this statement?

b. A researcher sends out 200 questionnaires, but 50 are returned because the addresses are inaccurate. Of the 150 delivered questionnaires, 50 are mailed back. However, 10 of these respondents wrote that they did not want to participate in the survey. The researcher indicates the response rate was 33.3 percent. Is this correct?
