Cross tabulations (also called contingency tables) show the statistical relationship between two categorical variables (or segment variable) by displaying their joint distribution. For example you can cross tabulate gender by age. Gender has 2 categories (male, female), whereas age can be categorized in a number of different ways, for example 4 categories (0-20 years old, 21-30 years old, 31-50 years old and 51 years old or more). A cross tabulation of gender and age would then result in a table with 8 cells. This table would show us how age is related to gender - that is, how many young women there are relative to how many older women, how many young men relative to older men etc.
