This article addresses the importance of randomization in designed experiments.
A key reason for this paper was to hopefully have more practitioners read George Box's referenced paper: "Must We Randomize Our Experiment?" My paper is essentially a trivial mathematical simulation showing how something can go wrong when a non-stationary disturbance is in the "background," and shows how randomization can address such issues. Box's paper provides some excellent advice, and I strongly advise practitioners to read it.
