The method, based on multiple comparisons such as those used in ANOVA, consists in identifying, for each characteristic studied on the JAR scale, if the rankings on the JAR scale are related to significantly different results in the liking scores.įor example, if a chocolate is too bitter, does that significantly impact the liking scores?

These correspond to ratings ranging from 1 to 6 for one or more characteristics of the product of interest. Data collected on a JAR (Just About Right) scale.
