Anybody know where I can find the standard deviations for baseball statistics for the 2005 season?

Question

This is for a statistics project. We're comparing individual players' statistics on the Giants, Mets, Yankees, A's, Marlins, and Dodgers for the 2005 season. Specifically, how their salary correlates with two primary statistics (Batting Average and # of Wins). Where can we find the MEAN and Standard Deviation of these statistics within the major league for the 2005 season so we can calculate P-values and Z-scores/T-scores?

Add all the values and divide by the number of values. This is your mean

Take the difference between each value and the mean and square it. Add all of these values and take the square root of this sum. That is your standard deviation.

I don't want answers like this. I know how to take STD. I'm just not willing to do it for over 700 baseball players.

Answer 1

Raw stats for 2005 can be found at

You'll have to compute means and variances yourself.

Answer 2

Answer 3

Be a chunk of history, although i'm a huge Yankee fan and the recent stadium is gorgeous bypass for the video games a Citi field (Mets) . for the reason that your no longer a fan years from now you have the capacity to say your first activity changed into on the all megastar activity lol taking section in field.
