⦁ A researcher was interested in the interaction between experience and mild intoxication on driving performance. They recruited 40 drivers to complete a driving simulation task. Half of the participants were highly experienced drivers, while the others were relatively inexperienced.
Participants all completed the task under two conditions: once when they were sober; and again after drinking a low dose of alcohol.
Reaction times to hazards that appeared in the simulation were taken as the DV. What statistical test should be used to analyse the data collected from this study?
Select one:
2×2 Repeated Measures ANOVA
3×2 Independent ANOVA
Two-Way Mixed ANOVA
Three-Way Independent ANOVA
⦁ How many data points would each participant provide for an experiment which is analysed using a Repeated Measures 2×2 ANOVA?
Select one:
1
2
4
⦁ Which of the following assumptions would you need to test before you interpret the results of a two-way mixed ANOVA, where both variables have 3 experimental conditions?
Select one:
Neither sphericity nor homogeneity of variance
Both sphericity and homogeneity of variance
Homogeneity of variance
Sphericity
