Appendix D, Table 1-4 provide extensive normative data collected from 1934 normal school children from ages 5 through 16 in Burgen County, New Jersey. Any child suspected of having any signs or symptoms of minimal brain dysfunction were excluded from the study. A comparison of normal with minimal brain dysfunction children was then conducted using an MBD group of 145 boys (ages 5-0 to 15-11) and 67 MBD girls as illustrated in Appendix D, Table 5. These T-Test comparisons at the p less than .001 level 62 of the 76 comparisons. Twelve of the remaining 14 comparisons were significant at the p less than .01 level and only two comparisons were found to be non-significant.
