Laya Heidari Darani

Hi Ankur,

First, I suggest that you explain more about your research. What I got is that you have two independent variables each of which has three levels, one dependent variable, and you want to compare these groups. In this case, you may use two-way ANOVA to compare the mean scores of these groups. However, if you'd like to have more technical answers--as I am not a statistician-- you can mention Prof. David L Morgan.

Best regards,

David Joubert

Use a factorial (or Multiway) ANOVA. It provides statistics for both main and interaction effects. Make sure that your groups are large enough, though.

This is clearly a 3x3 drug x route factorial experiment. Let it be sufficiently replicated.
