variance: the variance of a variate X is the arithmetic mean of the squares of deviations of X from the arithmetic mean of the observations and INVERTED Var(X) or Sigma square.

the positive square root of the variance of a variable X is known as standard deviation and is denoted by Sigma.

standard deviation = +(√V ar(X))
