A group of 132 female applicants to schools of nursing was given the WAIS Digit Symbol test and then the Wechsler-Bellevue Form Digit Symbol test. The time limit for each test was 1½ minutes, the standard time for WAIS Digit Symbol. The ages of the subjects ranged from 16 to 24. The mean score on WAIS Digit Symbol was 53.8 and the standard deviation was 10.8. The correlation coefficient between the two Digit Symbol tests was .88. For a subgroup of 59 subjects aged 18 and 19, the mean score on WAIS Digit Symbol was 53.6, the standard deviation was 10.8, and the correlation coefficient between the two tests was again .88. The group of 18-19-year-old females in the standardization sample obtained a mean score on WAIS Digit Symbol of 56.4 and standard deviation of 13.2. Apparently, the applicants to schools of nursing were more restricted in ability to perform on the Digit Symbol test than was the standardization sample of comparable age. The reliability coefficient for the 18-19 standardization group was estimated by correcting the obtained coefficient of .88 for the difference between standard deviations of the group of nurses and the standardization group. The resulting coefficient was found to be .92. This value is reported for the Digit Symbol test in Table 6 for age group 18-19.
