F Test Definition. 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.

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:

What is F-Test; Procedure for F-test; Sample Question; Solution ot Sample Question; Final Notes; 1. What is F Test. F-Test stands for Fisher’s test. Generally, this is the test used to Compare to variances. 2 ...
If we are using an F Test using technology, the following steps are there: State the null hypothesis with the alternate hypothesis. Calculate the F-value, using the formula. Find the F Statistic which is the critical value for this test. This F-statistic formula is the ratio of the variance of the group means divided by the mean of the within ...
