  • wtbyht --- person's weight divided by their height
  • verbal --- verbal SAT score
  • math --- math SAT score
  • soc_sat --- satisfaction with their social life on a 1 to 3 scale (3 is more)
  • acad_sat --- satisfaction with their academic performance to date on 1 to 3 scale (3 is

    more)

This brings up a dialog box which lists all your variables on the left side. You highlight the ones you want, then press the button in the middle of the screen to move the variables over to the right side:

Then press OK to run the program:

The result is the following table:
