| Research Abstract |
In psychological studies, the mean values of responses are often treated as a main concern of statistical data analysis, neglecting the variations of responses. In this study, we addressed the issue of multivariate analysis methods for analyzing the frequency distribution data of responses, and, utilizing the idea of mixture distribution, developed a principal component analysis method for interval-valued data, and a scaling method of successive categories for contingency table. Also the latter method was extended to contingency table with more than two variables
