Description

Three-Way Mixed ANOVA



Factor 1:



Time o 3 levels: Immediate, 30mins, 12hrs o Type: Within-Subjects Factor 2: Type o 2 levels: Words, pictures o Type: Within-Subjects Factor 3: Age o 2 levels: Old, young o Type: Between-Subjects Dependent variable: Correct recall

 

12 cells in the contingency table (2x2x3) so 12 conditions in the experiment 3 data points per cell of the contingency table, 2 groups, so 3x2=6 participants



Mauchly’s test result is significant for the interaction (0.045), so instead of sphericity assumed, we use Greenhouse-Geisser correction



Significant effect of age (0.007)





     

Significant main effect of time Non-significant time*age interaction Significant main effect of type Non-significant type*age interaction Non-significant time*type interaction Non-significant time*type*age interaction

  

Two within-subjects factors and one between-subjects factor Each within-subjects factor has its won associated error (residual) Each interaction that has a within-subjects element has its own associated error



Between-subjects factors have a single error between them...
