Nonresponse. When responses are not obtained from some of the individuals in the sample because either those individuals cannot be reached or refuse to participate, we have nonresponse bias. a. Discuss some of the dangers of nonresponse. b. Many sample surveys that are reported in the media have response rates as low as 10%. Explain the consequences of such low response rates in trying to generalize the results to the entire population.

- Decreased representativeness: If a significant portion of the sample does not respond, the sample may not accurately represent the population, leading to unreliable results. - Reduced statistical power: With fewer responses, the ability to detect true Show more…

Discuss some of the dangers of nonresponse. b. Many sample surveys that are reported in the media have response rates as low as 10%. Explain the consequences of such low response rates in trying to generalize the results to the entire population. a. Which of these are possible dangers of nonresponse? Select all that apply. A. People are more likely to give an answer that they believe will please the questioner. B. Response counts can be mismeasured due to the inaccuracy of the question. C. Those who do not feel strongly about the subject are less likely to respond. D. Those who feel strongly about the subject are more likely to respond.

Refer to the following table summarizing results from a study of people who refused to answer survey questions (based on data from "I Hear You Knocking but You Can't Come In," by Fitzgerald and Fuller, Sociological Methods and Research, VoL $11,$ No. I). In each case, assume that one of the subjects is randomly selected. What is the probability that the selected person refused to answer? Does that probability value suggest that refusal are a problem for pollsters? Why or why not?
