| Abstract: | Sensory evaluation data is sometimes collected using trinary category scales. Nonparametric data analysis for such data is discussed and a homogeneity statistic for trinary data is proposed which is simple enough to calculate with a pocket calculator. A statistic for identifying market segmentation in trinary data is also suggested. |
