Contingency Analysis

Examine Relationships between Two Categorical Variables

Use the Contingency platform to investigate the relationship between two categorical variables. The categorical variables can be nominal or ordinal. The analysis results include a mosaic plot, a contingency table of frequency counts and proportions, and Chi-squared tests of significance. You can interactively perform additional analyses and tests on your data, such as Analysis of Means for Proportions, correspondence analysis and association analyses. The Contingency platform is the categorical by categorical personality of the Fit Y by X platform.
