Suppose that some data set consisting of several groups with variables of continuous type is given and discrimination of the data is required. Then two discrimination procedures are available. The first is canonical discriminant analysis(CDA)which uses the variables as they are, while the second is Hayashi's second method of quantification(Q2), canonical discriminant analysis for categorized data. This paper compares the two procedures from two points of view; the value of correlation ratio and the misclassification rate when the results of the analysis are applied to the original data themselves. As an illustration two data sets were used. The first is based on medical claim units for the elderly compiled by Kosyu Eisei Shinkokai. The second is the famous iris data treated often in discriminant analysis. Neither of the two procedures can be said better than the other.
