Many factors determine the attendance at Major League Baseball games. These factors can include when the game is played, the weather, the opponent, whether the team is having a good season, and whether a marketing promotion is held. Popular promotions during a recent season included the traditional hat days and poster days and the newer craze, bobble-heads of star players. (Data extracted from T. C. Boyd and T. C. Krehbiel, "An Analysis of the Effects of Specific Promotion Types on Attendance at Major League Baseball Games," Mid-American Journal of Business, 2006, 21, pp. 21-32.)
