A comparison was done between the standard scores of the GAI and the FSIQ of the WISC-IV using 31 subjects. The mean difference between the GAI/ FSIQ standard score is 3.74. T tests of significance show that there is not a significant difference between the scores of the GAI and the Full Scale IQ. The Pearson r correlation (.963 @ .01 level) suggests there is a strong positive correlation between the GAI and the Full Scale IQ. In summary, the GAI is a good predictor of the FSIQ of the WISC-IV. More data is required to determine if a statistical difference between GAI and FSIQ scores exist with a bigger sample size.
