Abstract

This paper contrasts magnitude estimation (ratio) scaling and 9-point category scaling (hedonic scale) in terms of ability to detect differences in products and ability to illustrate the relation between product acceptance and formula ingredient level. Magnitude estimation shows more differences among products. Furthermore, magnitude estimation better reveals the relation between acceptance and ingredient level, making it easier for a product formulator to see how rapidly acceptance changes when the formulation is not at its optimum level.
