Coefficient of Variation Calculator
Calculate the coefficient of variation (CV) to measure relative variability. Useful for comparing the spread of datasets with different units or magnitudes.
The coefficient of variation (CV) is a standardized measure of dispersion.
Formula: CV = (σ / μ) × 100%
Why Use CV?
- Compare variability between datasets with different units (e.g., height in cm vs. weight in kg)
- Compare variability between datasets with different means
Interpretation
- CV < 15%: Low variability
- CV 15-30%: Moderate variability
- CV > 30%: High variability
Note: CV is only meaningful for ratio-scale data (data with a true zero point). It is not meaningful for interval-scale data like temperature in Celsius.
