Problem
Download the "Voting Behavior" data and the brief data description from the book's Web site. This is a data set manually compiled from counties all around the United States. The data are partially processed, that is, some derived variables have been created. Your task is to thoroughly preprocess the data by identifying the error and anomalies and proposing remedies and solutions. At the end, you should have an analytics-ready version of these data. Once the preprocessing is completed, pull these data into Tableau (or into some other data visualization software tool) to extract useful visual information from it. To do so, conceptualize relevant questions and hypotheses (come up with at least three of them) and create proper visualizations that address those questions of "tests" of those hypotheses.
