Bivariate Baseball Score Plots...?: OK...I came across this unbelievable baseball data crunching site. I don't have the faintest idea how one might use it. But surely, one might. And then one might tell me how I would apply it.

It's basically a way to sum up a group of games at a glance by aggregating their scores onto a graph. For instance, the 2006 Toronto Blue Jays graph. If I look down the "4" column, it tells me that they scored exactly 4 runs in 22 of their games (the little dots up top), and the results were as follows (running down the column):

  • 4-13
  • 4-8
  • 4-7 (4 such games)
  • 4-6 (5 such games)
  • 4-5 (2 such games)
  • 4-3 (6 such games)
  • 4-2
  • 4-1
  • 4-0
Every game they played is plotted on the graph, so you can tell at a glance what kind of scores they tended to win or lose by.

I felt a little pang of regret when I found "Montreal Expos" under "Historical National League."

Bivariate data can be used to create any number of useful analyses. For example, one could create some measure of offensive efficiency per game by plotting runs vs the sum of hits, walks, and opponents errors. All it takes is a little skill with Microsoft Excel, the patience and skill to do the research, and a 10-year-old budding mathematician who is a sports fan and is willing to do the data entry for very little cash. I have a limited amount of the first requirement, and neither of the latter 2.

Seems like a hell of a lot of work, but thanks for the explanation, DJE and Howard.
