Question about ANOVA.

I have a hypothetical scenario. So we're conducting a study. In the study there are four types of treatments (three are drugs, one is placebo), and two types of people. So 8 groups of people all together, right? Subjects are measured at baseline and then at another point say in three months or so.

My question is does time also count as an IV? So the IVs would be type of drug, type of person, and time? Making this a 3-Way ANOVA?

Answer #1

Yes this is a 3 way ANOVA problem. There are three independent variables here, type of drug, type of people and the time of testing. For tabulating and calculating their interrelationship, a 3 way ANOVA is the best way.
