Comparison of Coefficients of Variation
Use this calculator to compare two coefficients of variation (from independent samples), expressed as a percentage, and determine whether they differ significantly.
Required input
Enter the two coefficients of variation, expressed as percentages, and the corresponding number of cases.
Results
When the calculated P value is less than 0.05, the conclusion is that the two coefficients of variation are significantly different.
