(written as Variance)A measure of the dispersion of a set of numbers. It is the standard deviation squared. The variance of a population is the squared deviations of the measurements from their mean divided by the size of the population. The variance of a sample uses the sample means in the calculation of the squared deviations and the sample size minus one as the denominator. In accounting and budgeting practice, 'variance' is the difference between a budgeted amount and the outturn.
