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.
