Both calculators run independently — change the inputs on either side to compare results.
Statistics
Coefficient of Variation Calculator
Compute the coefficient of variation (CV), a dimensionless measure of relative variability defined as the standard deviation divided by the mean, expressed as a percentage. Used to compare variability across datasets with different units, magnitudes, or context — investment risk, biological variability, measurement precision.

Statistics
Variance Calculator
Compute population or sample variance from the sum of squared deviations and the sample size. The fundamental measure of how spread out a dataset is around its mean, and the building block of standard deviation, ANOVA, and most parametric inference.
