Contrasts in mixed ANOVA
I need help to explain the contrasts in ANOVA.
I have run a two-ways mixed anova (A = the within factor and B = the between factor). I have a main effect for A then B separately. I have also an interaction A*B.
To avoid the multiple comparisons in post hoc for the interaction A*B (due to a low number of subjects), I have performed custom contrasts based on my planned hypothesis. But, I don't understand the test that is performed in JASP, it's a T test ? I don't think so because I compared and it is not the same results...
If someone has the answer ? let me know ;-)
Thanks very much for any advice!
