This paper gives an illustration of exploratory data analysis with Hayashi’s Quantification Method III using graphics (hereafter we abbreviate this method as HQM III). It is shown that artificial data sets with ordinal structures can be expressed on the surface of a torus, and it is also pointed out that the torus suggests the results of HQM III. Some applications of HQM III to medical data using the graphical configuration are reported.
