Formula
CV = s / x̄.
As percent: CV% = (s / x̄) × 100%.
How to Use
- Enter mean x̄ and standard deviation s.
- It returns CV as a ratio and as a percentage.
Case Studies
x̄=50, s=5 → CV=0.1 (10%)
CV = 5 / 50 = 0.1 = 10%.
FAQ
When is CV useful?
Use it to compare dispersion across different units; avoid when the mean is near zero.
