  1. 1In a repeated measures ANOVA, the within-participant variability is divided into two components, what are they?
    1. AVariability between conditions and total variability
    2. BVariability between conditions and random variability
    3. CTotal variability and random variability
    4. DVariability between participants and random variability
  2. 2Which of the following is an important advantage of a repeated-measures ANOVA?
    1. AA different sample of participants serves in each condition, making it possible to compare different populations
    2. BIndividual differences do not contribute to unsystematic variance
    3. CA large number of participants is generally required, which provides a greater glimpse of the population
    4. DAll of the above
  3. 3A researcher reports ANOVA as F (2, 40) = 5.18, p = .01, how many conditions were involved in this study?
    1. A2
    2. B3
    3. C4
    4. D41
  4. 4How many participants were there in the experiment reported in question 3?
    1. A21
    2. B63
    3. C41
    4. D44
  5. 5Sphericity is an assumption in a repeated measures ANOVA. How is sphericity calculated?
    1. ABy looking at the variability within each condition
    2. BBy looking at the size of the differences in each condition
    3. CBy looking at the difference between the first and last condition
    4. DBy looking at the variability in difference scores between conditions
  6. 6The following table shows the results of a repeated-measures ANOVA, but the F-value is missing. what is the F-Value?Image for question 6
    1. A11.10
    2. B12.13
    3. C0.91
    4. D0.08
  7. 7Which of the following statements about the assumption of sphericity is NOT true?
    1. AIt is tested using Levene's Test in SPSS
    2. BIt is tested using Mauchley's Test in SPSS
    3. CIt is automatically met when an IV has only two levels
    4. DIt is the repeated measures equivalent of homogeneity of variance
  8. 8If the assumption of sphericity is violated, which correction is available in SPSS?
    1. AMauchly
    2. BLevene
    3. CGreenhouse-geisser
    4. DKolmogorov-smirnov
  9. 9The larger the F statistic is in a repeated measures ANOVA, the larger the ___________, compared to the ____________
    1. AVariation within individuals; variation between individuals
    2. BRandom variation; variation between conditions
    3. CVariation between conditions; random variation
    4. DVariation between individuals; variation within individuals
  10. 10A researcher wanted to see whether desensitization therapy was an effective treatment for hylophobia (fear of forests). She recorded levels of hylophobia in 20 participants at three points; before therapy, after therapy, and at a six-month follow up. The SPSS output from her data analysis is shown below. Which of the following statements is true?Image for question 10
    1. AThe data meets the assumption of normality
    2. BThe data violates the assumption of sphericity
    3. CThere was a significant reduction in hylophobia following desensitisation therapy
    4. DDesensitisation therapy did not affect hylophobia levels
