Summary
The objective of the mean analysis is to determine if, on average, the product scores Just About Right, or whether there is a skew of Too Much or Not Enough of an attribute. This method of analysis uses only the JAR data. While calculation of the JAR means is completed individually for each product, these means can be compared (see Appendixes I and J). Determining whether the mean is statistically different from the scale midpoint is discussed in Appendix F.
