A lot of people hypothesized that the lockout, amongst other variables, propelled yardage totals last year. In the same vein, they also hypothesized the gap between the elite and "the rest of of the league" would close due to this fact. Now, I want to preface this by saying this is not an overreaction thread. I'm merely going to be posting Week 1 yardage totals from 2011 and 2012, compare them, then ask a question.
The average YPG from Week 1 of 2011 was 253.5. The average YPG from Week 1 of 2012 is 256.75. The standard deviation however, is what I'm interested in. Math is not my strong suit, so if possible I'd really appreciate if someone could help me with this this. Regardless, from a quick glance over the #'s from each year, the gap did seemingly close.
Mean, Variance and Standard Deviation (2007-2012)
*4PT per passing TD
*1PT per 25 passing yards
*-1PT per INT
2007 QB Sats
Total #'s = 12
Mean (Average) = 18.1 PPG
Standard Deviation = 2.66 PPG
Variance = 7.08
Coefficient of Variation = 14.69%
2008 QB Stats
Total Numbers = 12
Mean (Average) = 17.56 PPG
Standard Deviation = 1.3 PPG
Variance = 1.69
Coefficient of Variation = 7.4%
2009 QB Stats
Total Numbers = 12
Mean (Average) = 18.56 PPG
Standard Deviation = 1.53 PPG
Variance = 2.34
Coefficient of Variation = 8.24%
2010 QB Stats
Total Numbers = 12
Mean (Average) = 19.04 PPG
Standard Deviation = 2.67 PPG
Variance = 7.12
Coefficient of Variation = 14.02%
2011 QB Stats
Total Numbers = 12
Mean (Average) = 20.73 PPG
Standard Deviation = 3.54 PPG
Variance = 12.56
Coefficient of Variation = 17.07%
2012 QB Stats (up until week 4)
Total Numbers = 12
Mean (Average) = 21.28 PPG
Standard Deviation = 2.60 PPG
Variance = 6.76
Coefficient of Variation = 12.22 %
*6PT per passing TD
*1PT per 20 passing yards
*-1Pt per INT

Standard Deviation = 2.18 PPG
Variance = 4.70
Coefficient of Variation = 8.96%
2009 QB Stats

2010 QB Stats

Mean (Average) = 26.16 PPG
Standard Deviation = 2.64 PPG
Variance = 6.96
Coefficient of Variation = 10.09%
2011 QB Stats
Total Number = 12
Mean (Average) = 28.43 PPG
Standard Deviation = 4.66 PPG
Variance = 21.70
Coefficient of Variation = 16.39%
2012 QB Stats (up until Week 4)
Total Number = 12
Mean (Average) = 29.44 PPG
Standard Deviation = 2.67 PPG
Variance = 7.14
Coefficient of Variation = 9.07%
If this trend does continue, does it make it so there wasn't any real value in drafting a QB in the first round? Would it have been better to wait until the later rounds?
