Cross tabulation (or crosstabs for short) is a statistical process that summarizes categorical data to create a contingency table.[1][2] They are heavily used in survey research, business intelligence, engineering and scientific research. They provide a basic picture of the interrelation between two variables and can help find interactions between them.

Some entries may be weighted, unweighted tables are commonly known as pivot tables.

Example[edit]

Sample # Gender Handedness
1 Female Right-handed
2 Male Left-handed
3 Female Right-handed
4 Male Right-handed
5 Male Left-handed
6 Male Right-handed
7 Female Right-handed
8 Female Left-handed
9 Male Right-handed
10 Female Right-handed

Cross-tabulation leads to the following contingency table:

Left-
handed
Right-
handed
Total
Males 2 3 5
Females 1 4 5
Total 3 7 10
