The issue of analyzing data from a designed experiment in coded form versus raw form was covered and illustrated numerically in Section 12.12. Consider a model with two main effects and an interaction term.
Â
(a) Show algebraically why the main effect model coefficients will be different for the two forms, and thus the p-values will differ.
(b) Use 12, 10, 21, and 28, respectively, and 23, 26, 18, and 14, respectively, as the two sets of response values for the treatment combinations in the example in Section 12.12 with the two sets of values being replicates of the treatment combinations used and show numerically that the p-values for the two main effects differ between the raw-form data and the coded-form data.
