In my experiment, 2 independent groups (patient vs. control) carried out 8 trials in which they had to chose between 2 options, one safe and one risky. 4 trials were formulated in terms of gain (2 with a low risk and 2 with a high risk) and 4 trials were formulated in terms of loss (2 with a low risk and two with a high risk).

All my IV, Group (patient vs control), formulation (gain vs loss) and level of risk (low vs high) are dichotoumous.

For example, I have a significant Group X Formulation interaction, but I am not sure how I can precisely observe the influence of the formulation within each group.
