Separately. Variance is a measurement of the spread between numbers in a data set. As the name implies, the percent variance formula calculates the percentage difference between a forecast and an actual result. Both of the above formula are basically the same except that Population Variance divides the result by N while Sample Variance divides the result by n-1. The Excel array formula is {=MMULT(TRANSPOSE(mvec),muvec)} The portfolio standard deviation in cell C14 is the square root of the portfolio variance, sig2px, in cell F10. VARIANCE Function Overview.
