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.

This procedure calculates the difference between the observed means in two independent samples. A significance value (P-value) and 95% Confidence Interval (CI) of the difference is reported. The P-value is the probability of obtaining the observed difference between the samples if the null hypothesis were true.

Description. The Test for one proportion can be used to test the hypothesis that an observed proportion is equal to a pre-specified proportion.. This test is not performed on data in the data table, but on statistics you enter in a dialog box. Required input. Observed proportion (%): the observed proportion, expressed as a percentage. Sample size: the .Use of the fitted equation. The predicted probability of a positive response can be calculated using the regression equation. When the regression equation is for example: probit = −2.61 + 6.36 × Dose probit = − 2.61 + 6.36 × D o s e. then .
