Table 2 shows the total number of scores made by the pro- 
vincial teachers, and the number of men and women making 
each score. The average score for the men is 77.0 and for the 
women 70.9. 
Fig. 1 shows graphically the data that are recorded in Table 2. 
The class interval is ten points. The regularity of the curves 
for the men and the women, and the fairly constant relation 
between the two, indicate that enough data were obtained to 
give representative results. 
Table 8 gives the average scores made by the teachers in the 
different provinces, which are all Tagalog. 
Prof. H. Otley Beyer, of the University of the Philippines, 
says*the following concerning the Tagalog group of Philippine 
peoples:
