    The object of traditional penalty analysis is to try to determine the effect “Too Much” or “Too Little” of a product attribute has on overall product liking. These product attributes have been called “Just-About-Right” or JAR variables, they are discrete and the middle value corresponds to a consumer response of “Just About Right.” There are two different approaches in determining the so-called penalties. Both are examined here.
