The file P11.34.xlsx contains data on the top 40 golfers in 2008. This was the year when Tiger Woods won the U.S. Open in June and then had year-ending surgery directly afterward. Using all 40 golfers, run a forward stepwise regression of Earnings per Round versus the potential explanatory variables in columns B–G. (Don’t use Earnings in column H.) Then create a second data set that omits Tiger Woods and repeat the regression on this smaller data set. Are the results about the same? Explain the effect, if any, of the Tiger Woods outlier on the regression.
