## Related Questions You need to use the variance and covariance functions in Excel 1. Calculate the covariance of the stock returns with respect to an index 2. Calculate the variance of the index 3. Divide the first number by the second. See the related link for a spreadsheet    Square the standard deviation and you will have the variance.    There only needs to be one data point to calculate variance. The standard deviation is the square root of the variance. So, if variance = 03 = 3 the std dev = sqrt(3) = 1.732  MS-Excel is a powerful worksheet &amp; you calculate , syncronize many hard calculation, so MS-Excel is called Excel. First we need to calculate within and between family variance components for half sib families. Additive variance is equal to 4 time the additive variance and Dominance variance equal to within family variance - (3/4) additive variance. Allows Excel to automatically calculate formulas in real time. When a referenced cell changes, the formula automatically updates. Calculate means Excel will evaluate formulas and functions to display the result. You can turn calculate to manual or auto. When it is on auto, everything is updated in real time. Manual will update when you open Excel or requires to you click the calculate button every time you want to see results. You can calculate quantity in Excel with the SUM function. The related link provides an excel template and some notes on how to calculate the sharpe ratio..pretty simple and effective. There is no single function in Excel.You calculate the mean (average).For each observation, you calculate its deviation from the mean.Convert the deviation to absolute deviation.Calculate the mean (average) of these absolute deviations. In a study using 9 samples, and in which the population variance is unknown, the distribution that should be used to calculate confidence intervals is Utilizing the visual basic functions built into excel worksheets you can calculate degrees of freedom.

Material Variance Cost Calculations: Standard (Budget) Price - Actual Price = Price Variance [Std (Budget) Price - Actual Price] / Std Price = Percent (%) Variance This years' sales plus last years' sales divided by 2 (Actual Effort -Planned Effort)/Planned Effort * 100 calculate the effective return (mean return minus the risk free rate) divided by the beta. the excel spreadsheet in the related link has an example. Suppose you have n observations {x1, x2, ... , xn} for a variable, X. Calculate m = (x1 + x2 + , ... , + xn)/n, the mean value. Calculate s2 = (x12 + x22 + , ... , + xn2)/n Then Variance = s2 - m2 = [mean of the squares] - [square of the mean] and the standard deviation = sqrt(Variance)
