Table 267. — Variables: Beta score X State. Groups IV and V: Colored draft. 



For all men who took beta only, alpha and beta only, beta and individual examination, and alpha, beta, and individual 



examination. 



Figure 21 gives a graphic comparison of the percentages of inferior, average, and superior 

 men for the 24 States of Group IV which have more than 100 cases. The States are arranged 

 from top to bottom according to the percentage of inferior men they have. The black portion 

 represents the percentage of inferior men, the lined portion tho percentage of average men, 

 and the clear portion the percentage of superior men. The number of cases for each State 

 is given in table 247. It will be seen from an examination of this chart that the States fall 

 roughly into three groups. The first group consists of northern States and is highest in intelli- 

 gence. The second group consists of the more northern and western southern States and is 

 intermediate in intelligence. The third group consists of the more southern and eastern 

 southern States and is lowest in intelligence. 



We now turn to the comparison between northern and southern States for the purpose of 

 which Group V was made up. The comparison is between the five representative northern 

 States of Group V and four States chosen to represent the South from Group IV. The four 

 States so chosen are Alabama, Georgia, Louisiana, and Mississippi. The distributions by 

 letter grade for the five northern States and for the four southern States are given together 

 for convenience of comparison in table 268. Figure 22 presents the data contained in this 

 table in graphic form. In this chart the area representing each State or group of States is 

 divided into a black portion which represents the percentage of inferior men, a barred portion 

 which represents the percentage of average men, and a clear portion which represents the 

 percentage of superior men. The significant difference between the northern and southern 

 States appears very strikingly and requires no further comment.
