I am using SPSS version 22, in windows 8. I am researching in cognitive psychology field. I am have designed two-way ANOVA. I have done the test for the main effects and also post-hoc (LSD and Bonferoni) for every of the categorical independent variables. What I need, and can not find, is post-hoc- test which shows all the possible interactions between all the levels of the first independent variable with all the levels of the second independent variable.
F.ex. If my first independent variable is A with three levels A1, A2, A3 and my second independent variable is B with three levels B1, B2, B3. I made post-hoc for A1A2, A1A3, A2A3. Also I did post hoc for B1B2, B2B3, B1B3.
And here is the problem I have: I need post-hoc- test for interaction of A1B1, A1B2, A1B3, A2B1, A2B2, A2B3, A3B1, A3B2, A3B3. I have been doing this before in Statistica- software, but in SPSS it does not give me option for post-hoc between different variables. In my case AxB (between all levels A and B together).
Thank you very much for the help.
