The coefficient of variation (CV) is a normalized measure of the dispersion of the frequency distribution. It is used to measure the relative variability and is expressed in %. In investments, the coefficient of variation helps you to determine the volatility, or risk, for the amount of return you can expect from your investment. The lower the ratio of standard deviation to mean return, the better your risk-return tradeoff. Use this online **coefficient of variation calculator** to find the CV for a range of values. This relative standard deviation calculator is capable of fetching consistently realible results all the time.

### Example:

If the range of values are : 2,3,4

#### Coefficient of Variation :

The mean of 2,3, 4 is (2+3+4) / 3 = 9 / 3 = 3

SD of 2, 3,4 is 1

Hence ,

COV = 1 / 3

CV = 0.333
