To assist in the drawing of conclusions from Tables 2.41 and 2.42, 

 the information they contain is presented in graphic form in Figure 

 2.41. Conclusions such as the following can be drawn from that figure 

 and the tables pertaining to Table 2.01 : 



(2.41) Only about 7 per cent of the students made a score less 

 than 55. This information can be read directly from Table 2.42 and 

 verified approximately from the r.c.f. curve of Figure 2.41. Also, 

 approximately 50 per cent of the students made a score of 98 or more, 

 a fact which corresponds closely with the fact that the exact median 

 is 97. Information of this sort can be obtained from Figure 2.41 by 

 reading horizontally from r.c.f- = -50 over to the r.c.f. curve and then 

 vertically downward to the scale of ACE scores.
