Attendance 2010 American League baseball games are played under the designated hitter rule, meaning that pitchers, often weak hitters, do not come to bat. Baseball owners believe that the designated hitter rule means more runs scored, which in turn means higher attendance. Is there evidence that more fans attend games if the teams score more runs? Data collected from American League games during the 2010 season indicate a correlation of 0.667 between runs scored and the number of people at the game. (mlb.mlb.com)
