    The chi-square approach looks at the relationship between “Just Right” and hedonic ratings for each product, using only the data from the “Not Just Right” sections of the scale. The objective of using a chi-square analysis is to determine if there are significant differences in liking between respondents that have rated the product differently on the JAR scales, i.e., to test the null hypothesis that there is no association between the JAR group and overall liking. For example, one could use the chi-square approach to determine whether respondents that rated the product as “Not Sweet Enough” differed from those respondents who rated the product as “Too Sweet.”
