A quality control engineer compared linear and quadratic models for predicting product defect rates based on production speed. The linear model predicts defects increase steadily with speed. The quadratic model shows defects decrease initially (as workers get into rhythm) then increase at high speeds (as workers make errors). Both models have similar predictive accuracy on the training data. Considering manufacturing psychology and process optimization, which evaluation is most sound?
