Hey Mojo, what does the variance actually tell us? I just read this: http://www.mathsisfun.com/data/standard-deviation.html and arriving at the answer seems fairly straightforward, but I don't really know how to interpret the answer.

What does variance = 21,704 actually mean in this example? I know what it is, the average of the squared differences from the mean, but it doesn't really mean anything to me.

Also, what can a standundering of variance teach us about poker?
