Answer
-
Total variability and random variability
-
Variability between conditions and random variability
-
Variability between participants and random variability
-
Variability between conditions and total variability
Question 2
Question
Which of the following is an important advantage of a repeated-measures ANOVA design?
Answer
-
A different sample of participants serves in each condition, making it possible to compare different populations
-
Individual differences do not contribute to unsystematic variance
-
A large number of participants is generally required, which provides a better glimpse of the population
-
All of the above

Question 5
Question
Sphericity is an assumption in a repeated measures ANOVA. How is sphericity calculated?
Answer
-
By looking at the difference between the first and the last condition
-
By looking at the size of the differences between conditions
-
By looking at variability in difference scores between conditions
-
By looking at the variability within each condition
Question 6
Question
Which of the following statements about the assumption of sphericity is NOT true?
Answer
-
It is the repeated measures equivalent of homogeneity of variances
-
It is tested using Levene's test in SPSS

It is automatically met when an independent variable has only two levels
-
It is tested using Mauchley's test in SPSS
Question 7
Question
If the assumption of sphericity is broken, which correction is available in SPSS?
Answer
-
Levene
-
Mauchly
-
Kolmogorov-Smirnov
-
Greenhouse-Geisser

Answer
-
Variation between conditions; random variation
-
Variation within individuals; variation between individuals
