Regression of Baseball Player Salaries Essay - 949 Words

Introduction The Major League Baseball (MLB) organization is a group of baseball teams that have made it to the Major League. The Major League Baseball data set provides the 2005 salaries of multiple Major League Baseball (MLB) teams as well as individual salaries of players within 30 teams (Lind, Marchal Wathen, 2008). The MLB data set gives information such as batting averages, wins, salaries, home runs, errors, etc (Lind, Marchal Wathen, 2008). Two specific teams stand out of the information when looking at their stats; St. Louis and Kansas City.

With St. Louis and Kansas City both being in the major league,†¦show more content†¦We could also test the differences in the season error rate of the two teams chosen and the stolen base total based on the performance. When performing the regression hypothesis test on the data we hope to prove that the th ere is a correlation between the performance of players and the salary that they are paid. When looking at the base data we are to conclude that there is a difference but by performing the hypothesis testing we can conclude that there are only some aspects of the sport of baseball that actually combine performance and pay.

We believe this is an interesting problem because it is traditionally believed that professional athletes play with hopes of earning a high salary, yet it often seems a batter’s performance is not linked to their salary (Jensen). Therefore, it seems as if the link between a player’s performance and their salary is different than their true performance. Performing a statisticalRead MoreWhy Teams With The Best Players Win The Most Games1156 Words   |  5 PagesThe governing wisdom in baseball is that the teams with the best players win the most games. Since the best players cost the most money, and only the wealthiest teams can afford the best players, the wealthier teams always win. Not exactly.
