DOE - replicates vs. repetitions
I need to to design an experiment to determine temperature - Temp influence on pH.Let's assume, temperature is a continuous variable in range [20,23].And pH is continuous as well, good within range [5,7], but perfect in the center.On a daily basis, in normal conditions we measure every sample 3 times (pseudoreplicates).Is 3 in this case number of replicates I should use in JMP? Or it's only repeti...
