2 way ANOVA
dependent variable and 2 fixed factors
My output table gives me P values for the fixed factors separately but I cannot figure out how to view the stats on how both fixed factors interact together.
Ex: 1st fixed factor=speed (3 speeds)
2nd fixed factor=substrate (3substrates)
i can see the interaction between the 3 speeds (what combinations are significantly different) and same with substrate.
What I can't see if what combinations of speed and substrate are significant (ex: the p values of speed 1 with substrate 1, 2 and 3)
I am working in SPSS and I am new to the program. Any advice would be much appreciated. Thanks in advance
