'''[[w:Cross tabulation|Cross tabulation]]''' (or '''crosstabs''' for short) is a [[w:statistics|statistical]] process that summarizes [[w:categorical data|categorical data]] to create a [[w:contingency table|contingency table]]. 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.
