It is calculated by dividing the standard deviation of an investment by its expected rate of return. C v frac sigma mu example. The coefficient of variation cv is a measure of spread that describes the amount of variability of data relative to its mean.

Statistical parameter in probability theory and statistics the coefficient of variation also known as relative standard deviation is a standardized measure of dispersion of a probability distribution or frequency distribution. It is often expressed as a percentage and is defined as the ratio of the standard deviation σ displaystyle sigma to the mean μ displaystyle mu. Begin aligned text cv frac sigma.

It has no units and as such we can use it as an alternative to the standard deviation to compare the variability of data sets that have different means. σ the standard deviation. The coefficient of variation is 0 42 8 19.

Calculating the standard deviation using the example above we found that. C v σ μ w h e r e.
