Appendix M: Using Grand Mean versus Mean of the Proportion of Respondents Who Scored the Product JAR

Source

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.
