Using cost-of-living data from the ACCRA Cost of Living Index in the file P2_19.XLS, examine the relationship between the geographical location of an urban area within the United States (e.g., northeast, southeast, midwest, northwest, or southwest) and its composite cost-of-living index. In other words, is the overall cost of living higher or lower for urban areas in particular geographical regions of the country? You will need to assign the given urban areas to one of any number of such geographical regions before you can produce pivot tables or other graphical tools in responding to this question.
