Abstract
Three measurement scales and models are considered, namely standardized, original, and centered. It is argued that the effects at the midpoint (of the experimental area) are relevant. Effects per unit and effects over the whole range are distinguished. Resolution IV designs permit unbiased estimation of these effects, even if quantitative factors are present.Keywords
