To examine whether the pattern of means for one IV changes at different levels of another IV, we look at
Interaction effects
Moderation effects examine the question of
When and for whom
When examining assumptions for factorial ANOVA, the guidelines apply to
each cell
With negatively skewed data, we would normally use which transformation function
Reflect (k - x)
What is the goal of using C and K in the transformation process
Avoid zero and negative scores
Using which functionto transform data would require reversing the direction of interpretation
inverse
what is the degrees of freedom for the interaction effect
(a-1) * (b-1)
To enhance clarity, you would likely plot the IV with more levels as
Horizontal axis
The different perspectives in explaining the interaction effect is a matter of
Clarity when conceptualizing

SPSS defaults to which type of sum of squares
Type III
Which method ignores the effect of the other IV when there are unequal sample sizes?
Wheighted mean
For repeated measures, the focus is on
Within subjects
When one IV is between-group and the other IV is repeated measure which ANOVA measure would you use?
Mixed
Which assumtion applies to repeated-measures but not simple one-way ANOVA

- Multiple imputation
- delete the case
- Full information maximum likelihood (FIML)
-use mean for that variable or case

split-plot
