PROPHET StatGuide: Contingency tables (cross-tabulation)


For cross-classified data, contingency tables (cross-tabulations) record the frequency for the values that fall into each possible combination of levels from two different factors. One of the factors is associated with the columns of the contingency table; the other factor is associated with the rows of the contingency table. Individual qualitative data values are simply grouped by the values of the classification variable. For individual quantitative data values, a classification may be created by defining intervals or cutpoints to bin the data into separate groups.
