Formula
(Desvio PadrĂ£o / MĂ©dia) Ă— 100
Step by Step
Desvio PadrĂ£o: 27.3861
MĂ©dia: 50.0000
CV = (27.3861 / 50.0000) Ă— 100 = 54.77%
Relativizing the Error
An error (standard deviation) of 10 centimeters—is it a lot or a little? It depends! If you are manufacturing pens, a 10cm error ruins the business (very high CV). But if you are cutting 10-meter trees, 10cm doesn't make the slightest difference (very low CV). This calculator gives you a percentage (e.g., 2%) so you can understand the severity of the error!
