Resource summary

Question 1

Question
In a factorial repeated measures ANOVA with 2 IV's (IV 'A' and IV 'B'), how do we partition the variance for SSm?
Answer
  • We split it into SSa and SSb
  • We split it into SSa, SSb and SSa*b
  • We split it into SSa and SSa*b
  • We don't split the variance beyond SSm

Question 2

Question
In a factorial repeated measures ANOVA with 2 IV's (IV 'A' and IV 'B'), how do we partition the variance for SSr?
Answer
  • Into SSr'a' and SSr'a*b'
  • Into SSr'a' and SSr'b'
  • Into SSr'a', SSr'b' and SSr'a*b'
  • We don't partition the variance of SSr.

Question 3

Question
In a factorial repeated measures ANOVA with 2 IV's (IV 'A' and IV 'B'), which formula do I use to calculate F for the main effect of IV 'A'.
Answer
  • MSa/MSr
  • MSa/DFa
  • MSa/MSb
  • MSa/MSr'a

Question 4

Question
If my study is a repeated measures factorial ANOVA, the relevant asumption I should be concerned about is ______________. If this assumption is met, I would expect to see that __________.
Answer
  • Homogeneity of variance; Levene's test should be significant
  • Homogeneity of variance; Levene's test should not be significant
  • Sphericity; Mauchlys test should be significant
  • Sphericity; Mauchlys test should not be significant

Question 5

Question
The following output shows the results of a two-way repeated measures ANOVA. The two IV's are treatment ('TREAT') and dosage ('DOSE'), some sections have intentionally been blacked out. Based on the level of output, how many levels of treatment were there?
Answer
  • 3
  • 1
  • 9
  • 2

Question 6

Question
Referring to the same output presented in question 5, how many levels of dosage were there?
Answer
  • 4
  • 3
  • 9
  • 5

Question 7

Question
Calculate the values marked 'A' and 'B'.
Answer
  • A = 83.488 B = 1730.560
  • A = 1730.560 B = 83.488
  • A = 34.078 B = 2379.49
  • A = 2379.49 B = 34.078

Question 8

Question
What are the results?
Answer
  • Two main effects and an interaction
  • No effects
  • Significant interaction effects
  • Only two main effects

Question 9

Question
Based on the results, which graph depicts the closest pattern of results?

Question 10

Question
<---
Answer
  • Dose 5 Treat 2
  • Treat 2 Dose 5
  • Dose 2 Treat 5
  • Treat 5 Dose 2
