Rounding two standard deviations to the nearest whole number (13) means that an average teams record would range from about 6894 to about 9468 about 95 percent of the time (reflecting the proportion of the area under a bell-shaped curve within two standard deviations of the mean). Of these three, pitching has eleven out of the nineteen most heavily correlated variables when compared to win percentage.

Here is the so-called "Pythagorean" formula for baseball: EXP (W%) = (RS)2 / [ (RS)2 + (RA)2] EXP (W%) is the expected winning percentage generated by the formula, RS is runs scored by a team, and RA is runs allowed by a team. Below are the results of error rate and fielding percentage, two important defense metrics, compared to win total for each team.
