Predicting Olympic Medal Counts: A Statistical Analysis of Socioeconomic and Demographic Factors at the 2004 Athens Games [1] Some interesting countries, such as Russia and Jamaica, are excluded from the data set because information was not available for all variables. 1. Add a dummy variable to the data set, representing whether the nation was the host of the Olympics. (Hint: The 2004 Athens Olympic Games were hosted by Greece .) Perform a correlation analysis on all of the variables in the data set, and show the results here in descending order of importance. Explain your results.

Show scatter diagrams of the two most important predictors, showing their relationship to “Medals”. Use labels to indicate interesting outliers, show a linear trend line, and write something intelligent about your graphs.
