3. When a data table appears, click on the words Create a Map. The system states: “Click on a data value in the table to map.” Note that the numbers in the table are now hyperlinked. Click in a cell with the data of interest to the study. The system will display the topics to be mapped. Check to see that the selection is appropriate and click the Show Map button.
