Cross-tabulation  (CROSS-TABULATION)

The basic data1, raw data1, primary data1, or crude data1 consist of a series2 of numbers3 or figures3 (cf. 155-2) which are put together in the form of a statistical table4. In such a table the data are generally classified with respect to certain variables5 or variates5 such as age, number of children, etc., or with respect to certain qualities6, characteristics6 or attributes6 such as sex. Where data are classified with respect to several variables or attributes simultaneously the tables are called cross-tabulations7. Summary tables8 give information in rather less detail than do individual tables9.
