What is CV%?
The Coefficient of Variation (CV) is a statistical measure used to describe the relative variability of a dataset. It expresses the standard deviation as a percentage of the mean.
CV% = (Standard Deviation ÷ Mean) × 100
Example
If the mean is 50 and the standard deviation is 5:
CV% = (5 ÷ 50) × 100 = 10%
General Interpretation
| CV% | General Interpretation |
|---|---|
| < 10% | Low relative variability |
| 10–20% | Moderate variability |
| 20–30% | High variability |
| > 30% | Very high variability |
Important: CV interpretation depends on the
scientific field and dataset. The thresholds above are
general guidelines rather than universal statistical rules.
CV is most meaningful when the mean is positive and meaningfully
different from zero.
