Summary/Abstract: This paper presents the use of graphical methods for the analysis of multi-way contingency table. Graphical methods for categorical data are well known and fully developed, however, visualizing categorical data is only now being developed. Many of these are specialized for particular types of tables and most are not readily available in standard software, and they are not widely used. In this paper we illustrate the use of mosaic displays and other graphical methods for the analysis of several multi-way contingency tables e.g. sieve plot, double-decker plot, fourfold plot. Second, we introduce several extensions of mosaic displays designed to integrate graphical methods for categorical data with those used for categorical data.
