- Cross tabulation
-
Cross tabulation is the process of creating a contingency table from the multivariate frequency distribution of statistical variables. Heavily used in survey research, cross tabulations (or crosstabs for short) can be produced by a range of statistical packages, including some that are specialised for the task. Survey weights often need to be incorporated. Unweighted tables can be easily produced by some spreadsheets and other business intelligence tools, where they are commonly known as pivot tables.
