Frequency Counts Based on the Joint Classification of the STS and GAC Factor Modals Resultant from the Extended Model of LNS+DS & Verbal+Performance+Achieve

STS Modal: 1 2 3 4 5 Subtotal (G-mean/sd)
GAC Modal: 1
MMR 24 14 36 3 1 78 (0.07/0.07)
Non-MMR 0 0 11 13 7 31 (0.43/0.19)

GAC Modal: 2
MMR 7 2 10 1 0 20 (0.12/0.09)
Non-MMR 1 2 28 23 15 69 (0.56/0.20)

GAC Modal: 3
MMR 0 0 0 0 0 0
Non-MMR 0 0 0 0 1 1 (0.71/NA)

GAC Modal: 4
MMR 5 3 10 1 0 19 (0.22/0.08)
Non-MMR 8 11 89 89 58 255 (0.72/0.16)

GAC Modal: 5
MMR 2 1 1 0 0 4 (0.24/0.06)
Non-MMR 4 9 120 148 63 344 (0.82/0.13)

GAC Modal: 6
MMR 1 0. 1 0 0 2 (0.41/0.27)
Non-MMR 0 3 39 66 25 133 (0.91/0.10)

GAC Modals: All
MMR 39 20 58 5 1 123 (0.11/0.10)
(G-mean/sd) (0.07/0.09) (0.09/0.07) (0.15/0.11) (0.17/0.10) (0.19/NA)
Non-MMR 13 25 287 339 169 833 (0.77/0.18)
(G-mean/sd) (0.39/0.13) (0.64/0.20) (0.68/0.18) (0.82/0.15) (0.86/0.15)

Total: 52 45 345 344 170 956 (0.68/0.28)

Note: MMR: The subgroup with mild mental retardation. Non-MMR: The subgroup without mild mental retardation. G-mean/sd: The mean and standard deviation of the factor mean scores of the G factor. The case weight used in the analysis for participants with MMR was removed for the tabulation. Modals 1, 2, …, 5 of the STS factor and 1, 2, …, 6 of the GAC factor are ranked from the lowest to the highest in the related abilities. The G-mean/sd values are means and standard deviations of the factor mean scores of the G factor for the marginal subgroups of the GAC and STS factors.
