  subject was given the WAIS-R IQ test and their Test (not the retest) scores
  were compared with their WAIS-R IQ scores.

   1. 50 100
   2. 60 115
   3. 65 120
   4. 40 96
   5. 35 100
   6. 40 85
   7. 60 115
   8. 55 105
   9. 50 103
   10. 45 90
   11. 52 120
   12. 48 105
   13. 51 110
   14. 49 95

   17. 37 95
   18. 63 112
   19. 50 100
   20. 50 100
