Design of experiments for dummies

摘要

Design of experiments (DoE) is considered complex by many persons in industry and hence not applied as widely as it could and should be. This article illustrates nine basic rules of DoE through a fictitious experiment to verify whether a new fertilizer would increase tomato yield more than commensurately, off-setting increased fertilizer cost. This is a simple one-factor, two-level experiment. The author asserts that most of the experiments performed by industry belong to this category.
