Tests
Tests the hypothesis that the population means of multiple
populations are equal.
Tests the ratio between the variation in sample means of several
populations compared to variation among the units within the
individual samples in a single factor experiment.
F
The distribution is used for the one-way ANOVA test.
Tests the ratio between the variation among the levels compared to
variation within the treatments in a two factor experiment.
F
