I am trying to perform a mixed factorial ANOVA with a 2(A: 1, 2) x 2(B: 1, 2) x 3(C: 1, 2, 3) design, with A as the between-subjects factor and B, C as within-subjects factors in SPSS.
The results showed a significant three-way interaction effect, which leads to examining the simple main effects and possibly the simple simple main effects.
However, I'm struggling with coding the proper syntax for the three-way interaction effect. I have tried multiple times, but it doesn't work.
If I want to look for interactions with every variable (e.g., B*C at A(1), B*C at A(2), A*C at B(1), etc.), which syntax would be the best fit?
Your help is greatly appreciated.
Thank you so much.
