Remember degrees of freedom: df =n+nz-2 n2 po st FEST One-Way Analysis of Variance One-Way Analysis of Variance is used when you want to compare the means or hore than two groups. This test can be used only if the backgrounds assumptions are satisfied such that it has independent ranpom samples, population are normal and population variance are equal.
