How this calculator works
CV=σ/|μ|.
Formula
CV=σ/|μ|Expresses dispersion relative to the magnitude of the mean.
Worked example
20 percent relative variation is a verified test case used by the calculation engine.
Assumptions and limitations
- The mean must be non-zero.
- Standard deviation must be non-negative.
- Interpretation of CV depends on the measurement scale and context.
Methodology & sources
This calculator uses deterministic, versioned calculation logic. The formula and verified examples above are part of the calculation definition used by CalcuMint. Technical calculation version: 1.

Frequently asked questions
What does CV measure?
It expresses standard deviation relative to the magnitude of the mean.
Why can the mean not be zero?
Division by zero would make the coefficient undefined.
