Blocking factors and hypothesis tests in ecology: Is your statistics text wrong?
Newman JA., Bergelson J., Grafen A.
We demonstrate that statistics textbooks differ in their prescription for the analysis of experiments that involve blocking factors. The differences in analysis may lead to differences in conclusions regarding the significance of experimental treatment effects. We outline the two approaches, discuss why they are different, and suggest when each approach may be applicable. We point out that simply following one's textbook may not be the best course of action for any particular situation.
