Variance
A measure of dispersion of a set of data points around their mean value. The mathematical expectation of the average squared deviations from the mean. The square root of the variance is the standard deviation.

variance
A statistical measure of the variability of measured datum from the average value of the set of data. A high variance, indicating relatively great variability, also indicates that the average is of minimal use in projecting future values for the data. Standard deviation is the square root of variance. Financial analysts use both statistical measures to weigh investment risk. Compare covariance. See also risk.

Variance

Permission to use a property in a manner that does not meet current zoning requirements.In order to gain a variance,the property owner usually has to show a hardship on the property—not on the owner—if the requested use is not allowed.
