4: Repeated Measures One-Way ANOVA Flashcards
1
Q
When is a repeated measures one-way ANOVA used?
A
When we have 1 IV with more than 2 levels.
2
Q
What are the assumptions?
A
Normality, sphericity (homogeneity of covariance), and sample size.
3
Q
What does Mauchly’s tell us about sphericity?
A
There is no difference between the covariance under each paired comparison of IV levels.
4
Q
Between IV level variation
A
Treatment effects and experimental error (random and constant).
5
Q
Within IV level variation
A
Experimental error (random).
6
Q
When should Greenhouse-Geisser be used?
A
When Mauchly’s test is significant.
7
Q
dfM =
A
k (number of IV levels) - 1
8
Q
dfR =
A
dfM x (n - 1) - where n is sample size.
