Variance
From Wikipedia, the free encyclopedia
This article is about the mathematical concept. For other uses, see Variance (disambiguation).
In probability theory and statistics, the variance is a measure of how far a set of numbers is spread out.
It is one of several descriptors of a probability distribution, describing how far the numbers lie from the mean (expected value).
In particular, the variance is one of the moments of a distribution. In that context, it forms part of a systematic approach to distinguishing
between probability distributions. While other such approaches have been developed, those based on moments are advantageous in
terms of mathematical and computational simplicity.
The variance is a parameter describing in part either the actual probability distribution of an observed population
of numbers, or the theoretical probability distribution of a sample (a not-fully-observed population) of numbers.
In the latter case a sample of data from such a distribution can be used to construct an estimate of its variance:
in the simplest cases this estimate can be the sample variance.

250 Game sample on ipoker I felt like I was running awful with all of these near FT bubbles.
But the truth of the matter is in that short of a sample it may seem like running poorly to keep coming up
short when in fact I may have been running good to even make 9 near FT bubbles in less than 250 games...
sigh at variance and how it works :(
I did however ship the $11reb $1k GTD for almost $2,700
Here's to running even better over my next 250 games :)
Have a great week and gl on and off the felt....
