In Table XLVI the pupils reported are grouped into classes 

 depending on time spent. Sixteen classes are indicated. Class 1 

 includes all pupils who had spent less than 25,000 minutes up to 

 the time of being tested. Classes 2 to 16 differ each from the 

 one next to it by 5,000 minutes. Children are found in each 

 class excepting 12 and 14. The figures before the dash indicate 

 the number of schools reporting pupils in a particular class; the 

 figures after the dash are for the number of individuals reported. 



That the amount of time spent varies greatly is evident on a 

 hasty glance at the table. In every grade one or more schools is 

 giving almost double the amount of time spent by the average of 

 the twenty cities. In the fifth grade one city gives almost three 

 times what two others give. If such different time distributions 

 are really important there should appear distinct differences in 

 the medians, and variabilities of the cities which follow different 

 methods. The facts as to this are shown in tables XL VII to LII.
