Key terms in survey questions are often not well understood, and such ambiguity can affect responses. As an example, the article "How Unclear Terms Affect Survey Data" (Public Opinion Quarterly [1992]: 218-231) described a survey in which each individual in a sample was asked, "Do you exercise or play sports regularly?" But what constitutes exercise? The following revised question was then asked of each individual in the same sample: "Do 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.
