In this paper, tone color analysis problem is actually studied based on the data rated by the semantic differential technique and points out that a semantic inconsistent correlation may be caused if the conventional method transforms the data of the ordinal scale into the interval one in order to calculate the correlation. The conventional method using the correlation information sometimes causes analytical ill results called Heywood case. Then, this paper studies the rating process and proposes a new association and factor analysis method not using the correlation information. The validity and usefulness of the proposed method, and the difference between the proposed one and the conventional one are shown and discussed by comparing both of the concretely proceeded results.
