    Abstract

    The Percent Difference from Norm analysis determines if the % JAR responses meet or exceed an established norm. If they do not, it also determines the direction of the imbalances of the JAR scale responses. The Percent Difference from “Just Right” analysis does not rely on an established norm, but compares the non-JAR responses to those in the “Just About Right” category. If a significant difference is found, the non-JAR responses are compared to each other. The analysis is conducted on one product-attribute combination at a time, but there is no limit as to how many products or attributes may be analyzed.
