Abstract: Scores from baseball games are bivariate data, with each variate being one team's score. Information can be obtained from viewing the distribution of baseball scores from a bivariate point of view. We offer a baseball scores plot, with each game being a point in a two-dimensional grid, and an algorithm, database, and this website to allow interested users access to the plots.

How it works:

  • Select a team from the upper left-hand menu. The plot will be displayed in the center portion of the window.
  • Select a year. By default, the team's latest year is shown. Here's a tip: after selecting a year, press the up arrow on your keyboard, and possibly the return key, to cycle through the previous years.
  • Select a split. A split is a partioning of a team's games based upon a variety of game parameters, e.g. the starting pitcher, the opponent, etc. Note that only one split is in effect at any time. Also, the splits are reset each time a new year is selected.
