f test example using QI Macros add-in for Excel Click and drag over your data to select it in Excel: Click on the QI Macros Menu > Statistical Tools > F & t Tests, and then select "F-test: Two-sample for Variance": QI Macros will prompt for a significance level (default = 0.05)...
The F-test examines the difference between the R2R2 in the two models. The critical value for an F2,450F2,450 is 3.01 (F.INV. RT(0.05,2,450) in Excel). The value of the test statistic is 2.17, which is less than the critical value, and so the null that the coefficient on the...
The F.TEST Function is used to calculate F statistic of two samples in excel internally and returns the two tailed probability of the of the F statistic under Null Hypothesis (H0). Note that F.TEST function does not returns the F test value, instead it returns it’s probability. If F....

The F.TEST value returned by theLINESTfunction differs from the F-test value returned by F.TEST. LINEST returns the F-statistic, whereas F.TEST returns the probability. Example To calculate the result of an F-test for two arrays as shown in the table below, please copy or enter the belo...
For example, the output of an ANOVA calculation often includes data for the F statistic, F probability, and F critical value at the 0.05 significance level. To return the critical value of F, use the significance level as the probability argument to F_Inv_RT. Given a value for probab...
