For each value, subtract the mean and square the result. This is the squared difference. Then find the average of the squared differences.
The coefficient of variation (CV) is defined as the ratio of the standard deviation $${\displaystyle \ \sigma }$$ to the mean $${\displaystyle \ \mu }$$, $${\displaystyle c_{\rm {v}}={\frac {\sigma }{\mu }}.}$$ It shows the extent of variability in relation to the mean of the population.
