CV
Coefficient of Variation Calculator
The standard deviation as a percentage of the mean, to compare spread across scales.

How it's calculated
CV = σ ÷ |μ| × 100%
The CV lets you compare variability between things measured on different scales, such as the precision of two lab methods. It only makes sense for positive data with a true zero (weights, times, prices), not for temperatures in °C or data that crosses zero.
