Crosstab Report Designer

Cross-tabluation uses two variables and tabulates the results of one variable against the other. An example would be the cross-tabulation of parity and SCC. Each milk test has number of lactation or parity (the columns of the table) and her SCC value (the rows of the table). So for each milk test, those pairs of values are entered into the appropriate cell of the table.

A cross-tabulation gives you a basic picture of how two variables inter-relate. It helps you search for patterns of interaction. Obviously, if certain cells contain is proportionately large (or small) numbers of cases, then this suggests that there might be a pattern of interaction.
