The online Coefficient of variation Calculator is used to calculate the coefficient of variation of a set of numbers.
In probability theory and statistics, the coefficient of variation (CV) is a normalized measure of dispersion of a probability distribution. It is also called unitized risk or the variation coefficient.
The coefficient of variation is defined as the ratio of the standard deviation to the mean:
cv = coefficient of variation
σ = population standard deviation
x1, ..., xN = the population data set
μ = mean of the population data set
N = size of the population data set
