Cross-Tabulation

• A technique for organizing data by groups, categories, or classes, thus facilitating comparisons; a joint frequency distribution of observations on two or more sets of variables

• Contingency table- The results of a cross-tabulation of two variables, such as survey questions

Cross-Tabulation
