While all the important facts are included in the foregoing 

 tables they are much more clearly seen where shown in graphic 

 form. In some of the graphs which follow only eighteen cities

 when these graphs Avere made. The inclusion of these two cities

found it is due to the fact that in one case the group included 

 twenty cities and in another only eighteen. 



Three sorts of graphs are shown. The first represents the 

 medians and may be designated Form I. The second represents 

 the variabilities and may be called Form 11. The third shows 

 dependability and is designated Form III. 



In Form 1 the cities are arranged on the graph from left to 

 right in an order determined by the number of problems attempted, 

 the city at the left showing the fewest attempts. The several cities 

 are indicated by figures placed at that part of the curve which 

 I'epresents the median of the city in question. The figures on
