This dataset is designed for teaching the Cook’s Distance statistic. The dataset is a subset of data derived from the U.S. Statistical Abstracts, 2012. The example conducts a simple regression that examines whether the median household income of a state predicts the percentage of people in a state that lack health insurance and then uses Cook’s Distance to evaluate whether any cases have a disproportionately large impact on the results. The dataset file is accompanied by a teaching guide, a student guide, and a how-to guide for SPSS.
