The graph of the frequency curves for these two groups, Fig. 3,is noteworthy. Only once did as many as two cases have the samescore in Group A. The whites, Group B, had slightly more casesdeviating from the norm, but still relatively few. It is possiblethat the Composite Score of the Achievement Test,
