Crosstabulation table
It is often difficult to analyze a crosstabulation simply by looking at the simple counts in each cell. The fact that there are more than twice as many PDA owners in the $25,000 - $49,000 income category than in the under $25,000 category may not mean much (or anything) since there are also more than twice as many people in that income category.

step Open the Crosstabs dialog box again. (The two variables should still be selected.)

step You can use the Dialog Recall button on the toolbar to quickly return to recently used procedures.

step Click Cells.

step Click (check) Row in the Percentages group.

step Click Continue and then click OK in the main dialog box to run the procedure.

A clearer picture now starts to emerge. The percentage of people who own PDAS rises as the income category rises.
