Formula:

F-Value = S12 / S22 Where, S12 is the variance of first set of values S22 is the variance of second set of values

F-Test: It is a kind of statistical test that uses F-distribution. That is, a statistical test in which the test statistic has an F-distribution under the null hypothesis. F-Test is used to compare statistical models that have been fitted to a data set, and identify the model that best fits the population from which the data is sampled. The name F-Test was coined by George W. Snedecor, in honour of Sir Ronald A. Fisher.

How to Calculate F Test Statistic: Given above is the F-Test formula which depends upon the variance of the given 1st and 2nd set of values. This formula can be applied to models with values that have been fitted to the data using least squares. You could also use this F statistic formula in ANOVA (Analysis of Variance) to assess whether any of the treatments is on average superior, or inferior, to the others versus the null hypothesis.

Calculate the F value in which the test statistics has an F-distribution under the null hypothesis using this online F-test calculator. This test in one-way Analysis of Variance (ANOVA) is used to assess whether the expected values of a quantitative variable within several pre-defined groups differ from each other.
