I am doing a test on doctors' training level and the number on duty. One IV is training level, the other IV is the number of doctors on duty. The DV is the number of patients seen.
There are two levels to training level (trained vs. untrained) and three levels to Number on Duty (one, two, and three).
I want to do a two-way ANOVA but I understand both independent variables need to be Categorical. I think my Number Deployed variable isn't categorical.
Can someone help me if this matters? Is there a different test I should use? Or is there a correction I can apply?
