Standard Deviation

Posted By: Bill Phipps

In Response To: Stick Challenge (Daniel Murphy)

Iancho made a post where he listed the Quartile PR for a few top players. Stick's quartiles were 1.19 2.02 and 2.64. His PR was 2.3 (this includes some live matches). Using the quartiles to back out a standard deviation yields 1.07 = 1 standard dev.
Checking my own matches shows a standard deviation of 1.21 with a mean of 3.8. It makes sense to me that the lower the PR the lower the standard deviation (for example, a player with a 1.0 PR would not have a 1.2 standard deviation).
