The engineering objective of statistical evaluation of factors concerning slope failure is to predict failure zones of a particular region by referring to the result of the case study analyses. Therefore, while generalizing those factor categories, maintaining high degree of universality in such evaluations is indispensable. Especially in geological factors, it is vitally important to consider this sufficiency. In this respect, our reserch is aimed at examining the applicability of the intermediate classification of geological factors in statistical analysis and its adequacy as an evaluation tool. Comparison of each analysis based on both minor and intermediate classifications is made, applying quantification method II. The results indicate that, (1) as far as multivariate analysis in slope failure is concerned, the intermediate classification of geological factors is very much justified from a view point of generality in classification and universality in analytical evaluation ; and (2) in regions with geological features containing fairly large lava boulders, a classification that takes into account the formation process may be indispensable.
