Descriptive Statistics; Distribution Plot with Box Plot           Back

These descriptive statistics resulted from treating each of the 32 NFL teams active from 1996 through 2007 as quarterbacks with 12 year careers and calculating their respective "career" ratings (note: substitutions made for Browns inactive years, Oilers = Titans etc. etc.).  Let me know your questions and/or concerns with regard to my approach.

Bears	Minimum	69.26	Std Dev	5.00
~ Bengals	Mean	78.03	Skewness	0.50
Colts	Maximum	91.26	Kurtosis	-0.10
