Frequently Asked Questions
The coefficient of variation (CV) is a statistical measure of the relative dispersion of data points around the mean. It is calculated as the ratio of the standard deviation to the mean, often expressed as a percentage. It is useful for comparing variability between datasets with different units or means.
A lower CV indicates less variability relative to the mean, while a higher CV indicates more variability. For example, a CV of 10% means the standard deviation is 10% of the mean. There is no universal threshold; it depends on the context.
The CV is typically used for ratio-scale data with a meaningful zero and positive values. If the mean is negative or zero, the CV becomes undefined or meaningless. This calculator will still compute a value, but interpretation may not be valid.
