Hey all. I've been playing around with some numbers, mainly standard deviation and how it pertains to baseball. I did a study a few days ago of all 30 teams, making a chart of ave runs and runs against, as well as standard deviation of runs scored and runs against and varience of runs scored and runs against. Let me explain what everything means.

I have the runs scored per game average and team ERA of everyteam listed, as calculated by me by taking all the scores of all 60 or so odd games played so far. I then calculated the standard deviation, which is to say, how much away from the average the team scores in a particular game. For example, a team that has played 6 games scoring the following runs: 7,3,7,3,7,3 has an average of 5 runs per game and a standard deviation of 2 runs.

I also have calculated the variance, which is commonly refered to as the "spread" of the numbers or what I call the "blow out/shut out factor". For example, a team playing six games scoring 7,3,7,3,7,3 has the same standard deviation as a team that has scored 7,3,8,2,6,4, but the second team should have a greater variance.

So far, I have found the study to simply explain in numbers how a team plays. For instance, the A's aren't really going to blow you out that much and aren't going to get blown out that much, but they will play a close game and pitch you well. They are going to bring a similar game every night. This is given by a relatively small standard deviation on both pitching and low variance in both.

Just wanted your thoughts. Thanks for reading...
