The purpose of this study is to propose an exploratory correlation analysis method for two or more variable groups. This analysis method can be used when there is no hypothesis about correlation structure of variable groups. It is easy to interpret simultaneously the correlation structure within each variable group and between variable groups. Through the results of computer simulations, this analysis method is shown to be effctive for analyzing correlation structure of two variable groups. The practical application of this method is demonstrated by using Eve's semantic data (Osgood & Luria, 1954).
