The f test statistic or simply the f statistic is a value that is compared with the critical value to check if the null hypothesis should be rejected or not. The f test statistic formula is given below: F statistic for large samples: F = σ21σ22σ12σ22, where σ21σ12 is the ...
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 ...
However, the f-statistic is also used in various tests such as regression analysis, the Chow test, and the Scheffe Test (a post-hoc ANOVA test).The F-test can be used to test the following hypotheses:The variances of two populations are equal. The variances of two samples are equal. ...
