Key terms in survey questions too often are not well understood, and such ambiguity can affect responses.

Question:

Key terms in survey questions too often are not well understood, and such ambiguity can affect responses. As an example, the article €œHow Unclear Terms Affect Survey Data€ (Public Opinion Quarterly [1992]: 218€“ 231) described a survey in which each individual in a sample was asked, €œDo you exercise or play sports regularly?€ But what constitutes exercise? The following revised question was then asked of each individual in the same sample: €œDo you do any sports or hobbies involving physical activities, or any exercise, including walking, on a regular basis?€ The resulting data are shown in the accompanying table.

Is there any difference between the true proportions of yes responses to these questions? Can a procedure from this chapter be used to answer the question posed? If yes, use it; if not, explain why not.
