Coefficient of Variance (CoV) is a non-dimensional value calculated by dividing the Standard Deviation of a data set by the algebraic mean (or Average) of the same dataset. Thus CoV = STDEV/AVERAGE. So, in Excel, at the bottom of a column of numbers representing your data set, say in cells B39 to B58, make cell B60 = AVERAGE(B39:B58), B61 = STDEV(B39:B58) and B62 = B61/B60. CoV is frequently expressed as a percentage, so B62 could be = 100*B61/B60

How can I calculate portfolio variance in Excel?
To calculate portfolio variance in Excel, you can use the formula SUMPRODUCT(COVARIANCE.S(array1,array2),array1,array2), where array1 and array2 are the returns of the individual assets in your portfolio. This formula takes into account the covariance between the assets and their individual variances to calculate the overall portfolio variance.
How do you Calculate Stock Beta in Excel?
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

How do you calculate variance covariance matrix for daily market prices of stock in excel?
To calculate the variance-covariance matrix for daily market prices of stocks in Excel, first, gather the daily prices of the stocks in a spreadsheet. Convert these prices into daily returns by using the formula: ( \text{Return} = \frac{\text{Price Today} - \text{Price Yesterday}}{\text{Price Yesterday}} ) for each stock. Once you have the daily returns, use the Excel function =COVARIANCE.P(array1, array2) to calculate the covariances between each pair of stock returns, and =VAR.P(array) for the variances of individual stock returns. Finally, organize these values into a matrix format to represent the variance-covariance matrix.

How do you calculate variance given standard deviation?
Square the standard deviation and you will have the variance.

How do we calculate variance
How do you calculate standard deviation if I know variance?
Standard deviation = square root of variance.
How many cases are needed for analysis of variance?
There only needs to be one data point to calculate variance.
How do you calculate standard deviation with a variance of 03?
The standard deviation is the square root of the variance. So, if variance = 03 = 3 the std dev = sqrt(3) = 1.732
