This article finds its venue in the recent discussion about survey quality and level of nonresponse (Groves, Dillman, Eltinge, & Roderick, 2002; Biemer & Lyberg, 2003; Groves, Presser, & Dipko, 2004; Weisberg, 2005; Singer, 2006). Nonresponse has traditionally been viewed as a key variable in judging the quality of a survey; however recent research has shown that low response rate is not a major problem unless respondents and nonrespondents systematically differ on the estimated statistics. If it can be demonstrated that these two groups do not differ substantially (Curtin, Presser, & Singer, 2000; Keeter, Miller, Kohut, Groves, & Presser, 2000), or that there is no systematic error on estimates, nonresponse is less of a problem.
Exit polls are one of only a few instances that allow for assessment of the level of survey error due to nonresponse, as population parameters can be compared
