were numerical responses, so they do not have any value labels that could be attached to them. You can see the actual numerical codes for each variable using the Data Browser window by clicking on the Tools menu, selecting Value Labels, and clicking Hide All Value Labels. When you do so, you will see the cases that were “Male” now display “0,” and the cases that were “Female” now display “1.” Or you can highlight (using either the direction keys or the mouse) a particular cell (e.g., “Male”). When you do so, the actual value is listed in a pane just underneath the icons.
