13 



uniformly superior to the median. City 14 in Figures I and III 

 begins lower in the third grade and makes upward steps from grade 

 to grade along the scale ; but at every point remains below the medi- 

 an. City 13 and city 4 similarly are superior in the third grade, 

 and by analogous upward steps maintain that superiority thruout 

 the other grades. That these steps are not the same in degree 

 as the steps of the median is probably due to the small number of 

 children or the character of their selection in a single class or 

 to the presence of a superior or inferior teacher or method 

 in a particular class or grade. On the other hand, the con- 

 ditions that place cities 13 and 4 above and city 14 below 

 are probably general conditions affecting the school situation 

 as a whole. In Figures II and IV, all the scores of Tables 3 

 and 4 are translated into graphic form. The median for each 

 grade is shown by a heavy horizontal line, and each of the 

 cities is represented by a short broken line above or below this 

 median as its score demands.
