Answer #1

There is onlyone factor or independent variable in one way ANOVA whereas in the case of two-way ANOVAthere are two independent variables.

In a one-way ANOVA, theone factor or independent variable analyzed has three or more categorical groups. A two-way ANOVA instead compares multiple groups of two factors.

The two-way ANOVA compares the mean differences between groups that havebeen split on two independent variables (called factors). The primary purpose of atwo-way ANOVA is to understand if there is an interaction between the twoindependent variables on the dependent variable.

Exampe:

Let us suppose that the Human Resources Department of a company desires to know if occupational stress varies according to age and gender.

The variable of interest is therefore occupational stress as measured by a scale.

There are two factors being studied - age and gender

The one-way ANOVA is a generalization of what other statistical test? ANOVA is a generalization of the two-sample t test for independent means. ANOVA is a generalization of Levene's test for differences between variations. ANOVA is a generalization of the paired t test for independent means. ANOVA is not related to any other tests. 2.
