MLB Competitive Balance for 2013

Changing gears for today I analyze the level of competitive balance for Major League Baseball during the 2013 regular season.  Using the Noll-Scully measure of competitive balance reveals that MLB was similarly balanced this season compared to recent history, with the NL having a Noll-Scully = 1.69, the AL having a Noll-Scully = 2.07 and a combined Noll-Scully = 1.89.

I am using the standard deviation of a population as opposed to the standard deviation for a sample in the calculations above.  If you are interested in doing this on your own, here is a step-by-step guide to calculate the Noll-Scully measure of competitive balance using Microsoft Excel.
