I ran an experiment to measure the effect of two drugs combined on cell apoptosis. I used 8 different concentrations of the first drug alone, and 8 different concentrations of the first drug combined with a constant concentration of the second. I measured cell viability using the MMT method.
Which ANOVA analysis would be best to use? I thought two way as I wanted to measure the effect at each concentration and compare it to each concentration of the first drug alone.
It was suggested to me to use one way as I am only measuring one factor, but I consider it to be two.
Any help would be appreciated.
