Formula and methodology
Formula: CV=population standard deviation/|mean|.
The coefficient of variation expresses spread relative to the size of the mean, which can help compare scales when a meaningful nonzero ratio exists.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Data values — Comma-separated finite numbers.
Worked example
| Input | Value |
|---|---|
| Data values | 85, 95, 100, 110, 110 |
Mean =100; CV ≈9.49%.
Assumptions and limits
- Values are numeric and have a meaningful ratio-scale mean.
- Population standard deviation is used for the supplied list.
- A mean near zero, negative-scale interpretation, and sampling uncertainty require separate judgment.
