2015 NCAA FBS Competitive Balance

Now that the NCAA FBS season is over, let's take a look at how competitive the "league" was this year. For the 2015 season the Noll-Scully Competitive Balance measure was 1.564 for all games played.  Here are previous NCAA FBS season's measures of competitive balance (2002-2012) and (2013-2014) for the league as a whole including all the post season games in the NCAA FBS.  For those that are interested in calculating this on their own, here is a step-by-step guide as to how to perform the Noll-Scully competitive balance calculation.

As you can see from the chart above, that competitive balance among NCAA FBS teams has not changed much from one year to the next.  In fact the average Noll-Scully is 1.526 for this time period.  Of those listed only the 2005 and 2014 NCAA FBS seasons were more competitive than the average (i.e. had a Noll-Scully that was less than one standard deviation below the mean) and the 2003 and 2013 NCAA FBS seasons were less competitive than the average (i.e. had a Noll-Scully that was greater than one standard deviation above the mean).
