Abstract
It is the purpose of the data analysis to clarify the characteristic of the phenomena and to find the meaningfull relations among them. From the point of view, a graphical description of the data is effective for the understanding of the structure of them and, in paticular, is important for the multiple analysis. In this paper, we consider the method of the graphical description of the correlation coeffcient, the multi correlation coefficient and the partial correlation coeffcient in the multiple analysis.It makes useful for the visualization of the complex relationship among the data. Moreover it applies to the choice of the variables and the multicollinearity.
