MLB Research Paper
Much research has been done to compare the salaries of MLB players. MLB players have increasingly large salaries year by year. Some may think that more money equals more wins. The higher paid players may or may not play for a team with a high payroll. It is hard to determine whether wins increase due to more money as there are many variables to consider. However, with some research we can obtain an idea if this holds true.
Our study consists of making a relationship between team salaries and overall wins. Do higher salaries produce more wins? The data set used shows the number of wins as well as the team salaries for each team. Here is what we know: The team with the highest number of wins for the season was the St. Louis Cardinals with 100 wins. The Kansas City Royals only won 56 games making them the team with the lowest wins. As for team salaries, the New York Yankees have the honor of being the highest paid team with a total salary of $208.3 million and the Tampa Bay Rays have the lowest team salary with only $29.7 million.
