F-test is utilized to test whether the two autonomous appraisals of populace change contrast altogether or whether the two examples may be viewed as drawn from the typical populace having the same difference. for doing the test, we calculate f-statistic is defined as: the f distribution is used in many cases for the critical regions for hypothesis tests and in determining confidence intervals. two common examples are the analysis of variance and the f test to determine if the variances of two populations are equal.
