How to Use Excel to Calculate Coefficient of Variation

The coefficient of variation is a statistical measure of the distribution or dispersion of data around mean. This measure is used to analyze the difference of spread in the data relative to the mean value. Coefficient of variation is derived by dividing the standard deviation by the mean.

Step

Identify the set of numbers for which the coefficient of variation is to be calculated. Enter the data on the Excel sheet. This example uses cells A2:A7, but your Excel file may use other cells.

Step

Use the function Stdev (number1, [number2],…) to calculate the standard deviation in Microsoft Excel. Input the formula =Stdev (A2:A7) for this example -- but enter your actual cell usage in your Excel file -- in a blank cell and press Enter to calculate the standard deviation.
