An F-test is a statistical test that compares variances. It is used to determine if the variances of two samples, or if the ratios of variances among multiple samples, are significantly different.

An “F Test” refers to any test that uses the F-distribution and f-statistic. Typically, when people mention the F-Test, they are referring to the F-Test to Compare Two Variances.
