This excercise gives you a chance to examine an age old social science dispute, whether hitting or pitching wins ball games. Help shed light on this dispute by, turning to a recent almanac and the Major League Baseball website (http://mlb.mlb.com/index.jsp) to collect winning percentages, team batting averages, and team earned run averages for all the teams in either the American or the National League for one year. Use data collection techniques similar to those you used for the last few excercises, this time collecting data on three variables rather than two. Moreover you should use the data analysis techniques of each exccercises this time examining the relationship between winning percentage, and team batting average on the one hand, and and winning percentage and team earned run average on the other. Are both batting average and earned run average associated with winning percentage? Which would you say is more strongly associated with it? Why? Write a brief essay in which you state how your analysis bears on this research question.
