- Summary:
- This method describes a statistical procedure to compare a single mean to its JAR scale mid-point. It will determine if a product attribute is perceived to be significantly different from the ideal. When an attribute is significantly different from the mid-point, conclusions can also be made about the direction of the difference. This analysis is designed to compare a single product/attribute combination to its center-point, and is not appropriate for the comparisons across products or attributes. Comparisons among multiple products in the same test are limited to statements as to how they each relate to the JAR scale mid-point or Ideal value. Note that the Ideal value refers to the JAR scale mid-point, and is not related to a specific gold standard product.
