Contingency Table and Cross-Tabulation are provided as separate procedures to enable the user to analyse contingency tables using two distinct data types. The main difference between the two is that while the Contingency Table procedure accepts frequency count data already formed into a table, Cross-Tabulation will generate a frequency counts table from categorical variables. These can be numeric or string variables containing a limited number of distinct values. The form of output and the statistics reported are similar for the two procedures, with the exception of Stratified Analysis which is only available for multi-way cross-tabulations. Both procedures report an extensive set of statistics, including those covered under Binomial Proportion, Unpaired Proportions and Paired Proportions procedures. Information common to both procedures will be discussed in section 6.6.2. Cross-Tabulation.
