In particular, we seek the Var[h2], where the variance is just the 2nd central moment, and express the answer in terms of central moments of the population: CentralMomentToCentral[2, h2] We could just as easily find, say, the 4th central moment of the sample variance, as: Example of Cost Variance Formulas. ABC International is calculating the cost variance for its usage of steel. It spent $80,000 during the past month on steel, and expected to spend$65,000. Thus, the total cost variance is \$15,000. This cost variance is comprised of the following two elements: Material yield variance. ABC used an extra 70 tons The portfolio variance formula is used widely in the modern portfolio theory.

Variance: σ 2 = 206 2 + 76 2 + (−224) 2 + 36 2 + (−94) 2 5 = 42436 + 5776 + 50176 + 1296 + 88365 = 1085205 = 21704 Variance Formula: Variable Overhead Efficiency Variance = (Standard Hours X Standard Variance Overhead Rate Per Hour) – ( Actual Hours X Standard Variable Overhead Per Hour Fixed Overhead Spending Variance If you want to create a formula using any of these variance functions, you’ll need to use a set structure. The structure remains the same for each six functions: =VAR(value1,value2, …) =VAR.S(value1,value2, …) =VARP(value1,value2, …) =VAR.P(value1,value2, …) =VARA(value1,value2, …) =VARPA(value1,value2, **…)** The formula is =VAR.S(select data) The reason you want to use VAR.S and not VAR.P (which is another formula offered) is that often you don't have the entire population of data to measure.
