Analysis of cross-classifications using Crosstabs

The crosstabulation table is the basic technique for examining the relationship between two categorical (nominal or ordinal) variables, possibly controlling for additional layering variables.

The Crosstabs procedure offers tests of independence and measures of association and agreement for nominal and ordinal data. You can also obtain estimates of the relative risk of an event given the presence or absence of a particular characteristic, and you can test for significant differences in column proportions in the crosstabulation table.
