What is a Factorial ANOVA?

It is an independent ANOVA with two or more IVs.

2

What is 3x3 design?

What are the three effects found in a Two-Way ANOVA?

There are two main effects (one for each IV) and the interaction effect.

4

What test must be used to check the homogeneity of variance?

Levene's Test (should be non-significant).

5

When interpreting an interaction graph: when do we know there is a significant interaction?

If the lines cross or are not parallel.

6

Where interpreting an interaction graph: when do we know there is a non-significant interaction?

If the lines do not cross or are parallel.

7

What is a simple effects analysis?

It's a graph which breaks down the interaction effects.

8

What can SPSS Syntax be used for?

Time saving.
Doing extra stuff (like a simple effects analysis).

9

What is the general SPSS Syntax for running a simple effects analysis?

GLM DV by IV1 IV2
/EMMEANS = TABLES(IV1*IV2)COMPARE(IV)

10

Why are significant interactions important?

This is because they can potentially make the main effects redundant (and can be more interesting!).
