π Coefficient of Variation Calculator
Compare relative variability between datasets of different scales. Paste numeric values to compute sample and population coefficients of variation (CV), accompanying mean, and standard deviations.

Insights
- No values analysed yet.
How to Use
- Paste or type your dataset into the values field.
- Click Calculate CV to get sample CV (uses sample standard deviation) and population CV.
- Review the summary to understand relative spread; a higher CV means greater variability relative to the mean.
- Check insights for mean near zero warningsβCV becomes unstable when the mean approaches zero.
- Clean or reset inputs to evaluate another dataset.
Formula Reference
- Sample CV = \( \frac{s}{\bar{x}} \times 100\% \)
- Population CV = \( \frac{\sigma}{\mu} \times 100\% \)
