In probability theory and statistics, variance, is the expectation of the
squared deviation of a random variable from its mean, informally, it
measures how far a set of randon numbers are spread out from their
average value. Variance has a central role in statistics where some ideas
that use it include descriptive statistics, hypothesis and goodness of fit.
Variance is an important tool in the sciences. The variance is the square
of the standard deviation, the second central moment of a distribution
and the covariance of the random variable with itself and is represented
by o.2, s.2 or VAR (X)

Variance is a measurement of the spread between number in a date set and measures how far each number in the set is from the mean. Variance is
calculated by taking the difference between each number in the set and
the mean, squaring the difference to make them positive and dividing the
sum of the squars by the number of values in the set.

I sure hope you consider all above the next time you use VARIANCE.
