Counts vs. Percentages
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.
- Open the Crosstabs dialog box again. (The two variables should still be selected.)
- You can use the Dialog Recall button on the toolbar to quickly return to recently used procedures.
- Click Cells.
- Click (check) Row in the Percentages group.
- 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.
