III. COEEELATIOX OF I. Q.'s AXD TERM GRADES 



To determine the degree of correlation between the 

 I. Q. 's and term grades of the pnpils, each section is di- 

 vided into quintiles on basis of the I. Q. 's of the students 

 in it. These quintiles are marked 1, 2, 3, -i, and 5 begin- 

 ning with the quintile composed of pnpils with the higher 

 T. Q.'s. Likewise the grades of the pnpils in each sec- 

 tion in each subject are divided into quintiles and are 

 marked 1, 2, 3, 4, and 5 beginning with the quintile com- 

 posed of the higher grades in each subject. The two 

 charts which follow show the two sections with the 

 identiiication number of each student in each section, 

 the I. Q. of each student, the L Q. quintile and each 

 subject quintile in which the student's grades fall for 

 both terms.
