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....
F-statistic (the critical value for F-Test) is determined by the formula $$F=\frac{s_X^2}{s_Y^2}$$ If the variances are equal, then the ratio of the variances is $1$. The larger sample variance should be in the numerator of the F-ratio and the smaller sample variance in the...
error value. The F-test value that is returned by theLINEST functiondiffers from the F-test value that is returned by the FTEST function. LINEST returns the F statistic, whereas FTEST returns the probability. Example Copy the example data in the following table, and paste it in cell A1 o...
The FTEST value returned by theLINESTfunction differs from the F-test value returned by FTEST. LINEST returns the F-statistic, whereas FTEST 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 below fo...
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 probabil...

If Deg_freedom2 is < 1 or Deg_freedom2 is ≥ 10^10, F.INV.RT returns the #NUM! error value. F.INV.RT can be used to return critical values from the F distribution. For example, the output of an ANOVA calculation often includes data for the F statistic, F probability, and F cri...

Once the F-statistic is calculated, you compare the value to a table of critical values that serve as minimum cutoff values for significance.Here are all the observational notes using the F.DIST function in Excel Notes :The function only works with numbers. If any argument other than ...
