The file Home Price Index.xlsx contains an index of home prices and a seasonally adjusted (SA) version of this index for several large U.S. cities. It also contains a condo price index for several large cities and a national index. Use the tools in this chapter to make sense out of these data, and write a report of your findings. Some important questions you can answer are the following: Are there trends over time? Are there differences across cities? Are there differences across months? Do condo prices mirror home prices? Why are seasonally adjusted indexes published?
