ANOVA

I CANNOT GET MY HEAD AROUND THIS QUESTION?

An experimenter is interested in the how drugs and expectations of their effects interact and effect alertness. They gave half of their participants a stimulant, while the other half received a placebo. Within each drug condition, half of the participants were told the tablet they had taken was a stimulant, while the other half were told it was a depressant. Fifteen minutes after taking the tablets, all participants completed a standardised alertness questionnaire, producing a single alertness score. What statistical test should be used to analyse the data collected from this study?

Two-Way Independent ANOVA
Two-Way Mixed ANOVA
One-Way Independent ANOVA
One-Way Repeated Measures ANOVA
