One-Way vs Two-Way ANOVA: Differences, Assumptions and …
WebIn one-way ANOVA, we want to compare t population means, where t > 2. Therefore, the null hypothesis for analysis of variance for t population means is: H 0: μ 1 = μ 2 =... μ t. The alternative, however, cannot be set up similarly to the two-sample case. If we wanted to see if two population means are different, the alternative would be μ 1 ...
