Coefficient of Variation Calculator
Measure relative spread: the standard deviation as a percentage of the mean, for a sample or a population.

Mean
x̄ = Σx ÷ n
144 ÷ 8 = 18
Sample standard deviation
s = √(Σ(x − x̄) to the power of 2 ÷ (n − 1))
√(192 ÷ 7) = 5.237229366
SD as a % of the mean
CV = SD ÷ |x̄| × 100
5.237229366 ÷ 18 × 100 = 29.0957187%
How it works
CV = standard deviation ÷ mean × 100 (sample SD uses n − 1, population SD uses n)
