However, the square root of variance is the standard deviation, and that is If A is a vector of observations, the variance is a scalar. If A is a matrix whose columns are random variables and whose rows are observations, V is a row vector containing the variances corresponding to each column. If A is a multidimensional array, then var(A) treats the values along the first array dimension whose size does not equal 1 as 2019-05-29 · The percent variance formula shows how much something changes between two periods.
