I wanted to play with stats from the last few years, but all I could get was stats from 2005. I wanted to look at the standard deviations of hitter statistics, and try to establish what standard in each category should be especially useful. First, I eliminated everyone with under 200 at-bats, because it would just drag down all of the R HR RBI numbers, then I found the mean totals, then the standard deviations, then the numbers at 1 standard deviation above the mean (a point where 80% of players should get less than this number), 2 STDDEV's (97%) and 3 (99%). I put them together to form average joe (whose numbers you should be able to find on the WW), and then the standard deviations

R HR RBI SB AVG

AVG Joe 60 14 57 7 .269

STDDEV1 84 24 84 17 .295

STDDEV2 109 34 110 27 .320

STDDEV3 132 44 138 36 .347

Of course, few players ever get numbers even close to STD DEV 3, but there are some interesting things to note from these numbers. First, other than the SB, STDDEV3 looks a lot like PUjols to me. Second, standard deviation for both SB and HR is roughly the same (10 vs. 9.88), but roughly twice as many HR are hit each year. Third, BA should be easier to get strong numbers in than most other categories, considering that 1 STD DEV from the mean is .295 which is better than most FB teams average.
