1In a repeated-measures ANOVA, the within-participant variability is divided into two components. What are they?
- ATotal variability and random variability
- BVariability between conditions and random variability
- CVariability between participants and random variability
- DVariability between conditions and total variability
2Which of the following is an important advantage of a repeated-measures ANOVA design?
- AA different sample of participants serves in each condition, making it possible to compare different populations
- BIndividual differences do not contribute to unsystematic variance
- CA large number of participants is generally required, which provides a better glimpse of the population
- DAll of the above
3A researcher reports an ANOVA as F (2, 40) = 5.18, p = .01. How many treatment conditions were compared in this experiment?
- A4
- B41
- C2
- D3
4How many participants were there in the experiment reported in question 3?
- A21
- B41
- C44
- D63
5Sphericity is an assumption in a repeated measures ANOVA. How is sphericity calculated?
- ABy looking at the difference between the first and the last condition
- BBy looking at the size of the differences between conditions
- CBy looking at variability in difference scores between conditions
- DBy looking at the variability within each condition
6Which of the following statements about the assumption of sphericity is NOT true?
- AIt is the repeated measures equivalent of homogeneity of variances
- BIt is tested using Levene's test in SPSS
- CIt is automatically met when an independent variable has only two levels
- DIt is tested using Mauchley's test in SPSS
7If the assumption of sphericity is broken, which correction is available in SPSS?
- ALevene
- BMauchly
- CKolmogorov-Smirnov
- DGreenhouse-Geisser
8The larger the F statistic in a repeated-measures ANOVA, the larger the _____________ compared to the _________

- BVariation within individuals; variation between individuals
- CVariation between individuals; variation within individuals
- DRandom variation; variation between conditions
