Textbook Problem

A researcher conducts an independent-measures, two-factor study with two levels of factor *A* and three levels of factor *B*, using a sample of *n* = 12 participants in each treatment condition.

**a.** What are the *df* values for the *F*-ratio evaluating the main effect of factor *A*?

**b.** What are the *df* values for the *F*-ratio evaluating the main effect of factor *B*?

**c.** What are the *df* values for the *A*-ratio evaluating the interaction?

**a.**

To determine

The *df* values for the *F*-ratio evaluating the main effect of factor *A.*

Explanation

**Given info:**

In a two factor independent-measures study, there are two levels of factor *A* and three levels of factor *B*. The number of participants in each sample is

**Calculation:**

Let
*A* and factor *B* respectively. Let *m* represents the total numbers of treatment conditions. There are two treatment conditions for factor *A* and three treatment conditions for factor *B*. Let *n* represents numbers of participants in each treatment.

Then,

The degrees of freedoms corresponding to

**b.**

To determine

The *df* values for the *F*-ratio evaluating the main effect of factor *B.*

**c.**

To determine

The *df* values for the *F*-ratio evaluating the interaction*.*
