In order to investigate statistically the accuracy of brand judgement by the sense of smell, this report states the development of statistical method on the description of the accuracy of judgement. The authors considered about the accuracy of brand judgement, the description of group character, the similarity between brands, and the relation between the similarityamong brands on odor judgement and the difference of general chemical values.The obtained results were as follows : (1) The authors computed the eigen value and eigen vector from data matrix (score of panel). This eigen value is used as the measurement of accuracy of judgement.(2) The accuracy of brand (A, B, C, D, E) judgement by the sense of small was significant.(3) The accuracy of the production panel was higher than the business panel on brand judgemet.(4) There is something about the odors of brand A and B which distinguishes them from others.(5) A similarity between brand C and E was recognized, but a similarity between brand A and B was not recognized.(6) The relation between the similarity among brands by odor judgement and the difference of general chemical value were not recognized.
