In a two-factor analysis of variance, a main effect is found when there is a the difference between the largest treatment mean and the smallest treatment mean

A main effect is defined as. differences in means over levels of one factor collapsed over levels of the other factor. the difference between the grand mean and zero. is the effect of one factor at a given level of a second factor. a change in the simple two way interaction over levels of the third factor.

agree or not? Question 1: what is a one-way analysis of variance used for (Section 12-2)? One-way ANOVA (Analysis of Variance), is a statistical test that compares the variance in the group means within a sample while considering only one independent variable or factor. The hypothesis based test that is aimed to evaluate multiple mutually exclusive theories about data. In a one-way ANOVA there will be two different hypotheses. Meaning a test is done with two groups to see whether...
