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.

MedCalc uses the test by Forkman, 2009.
