Coefficient of Variation Calculator

Express variability relative to the mean.

Coefficient of variation (%) 15

Formula: CV = σ ÷ mean × 100

Step-by-step with your numbers:

1. Values used:

2. Standard deviation = 15

3. Mean = 100

5. Coefficient of variation = (15 / 100) x 100 = 0.15 x 100 = 15%

Did we solve your problem today?

CV compares the spread of datasets with different units or scales.

The math behind it

CV = standard deviation ÷ mean × 100. Lower means more consistent data.

σ 15, mean 100 → CV 15%.

Why use CV?

It's unitless, so you can compare variability across different measurements.
