Abstract:

An exit poll is an unbiased probability sample of voters exiting polling places on Election Day. The sample provides an estimate with sufficient precision to identify a winner and permits the academic study of why people vote as they do. Results are presented in a live election night television broadcast. Exit polls are ambitious class projects with all advantages of other sampling projects and one feature seldom found in statistical applications. Within 12 to 24 hours in most years, the vote tally is complete and the validity of statistical inference is demonstrated by comparing the sample projections and confidence intervals to the true parameter value!
