The F Value is calculated using the formula F = (SSE 1 – SSE 2 / m) / SSE 2 / n-k, where SSE = residual sum of squares, m = number of restrictions and k = number of independent variables. Find the F Statistic (the critical value for this test). The F statistic formula is:
F test can be defined as a test that uses the f test statistic to check whether the variances of two samples (or populations) are equal to the same value. To conduct an f test, the population should follow an f distribution and the samples must be independent events.

Find the expected number \ (E\) of observations for each cell based on the assumption that the two factors are independent (that is, just use the formula \ (E= (R\times C)/n\)). Find the value of the chi-square test statistic \ (\chi ^2\). Find the number of degrees of freedom of the chi-square test statistic.
This example teaches you how to perform an F-Test in Excel. The F-Test is used to test the null hypothesis that the variances of two populations are equal. Below you can find the study hours of 6 female students and 5 male students. H 0: σ 12 = σ 22. H 1: σ 12 ≠ σ 22. To perform an F-Test, execute the following steps. 1.
