56 PSYCHOLOGICAL METHODS OP TESTING INTELLIGENCE 



them now, and from them I have prepared the fig- 

 ures that appear in Table V. These figures, which 

 must be regarded as strictly provisional, merely in- 

 dicate with what percentual frequency all the tests, 

 taken collectively, for which I have the data, have 

 been passed, and this, it should be noted, for the 

 three older groups of children only. 14 



TABLE V. 

 PERCENTAGE OF TESTS PASSED IN CERTAIN AGE-LEVELS AT BRESLAU. 



9-12 9 and 10 11 and 12 



9- Year Vorschule Pupils 70 77 64 



9-Year Volksschule Pupils 60 81 34 



10- Year Volksschule Pupils 70 86 46 



The first column shows that the 9-year old Volks- 

 schule pupils rank in the number of tests passed 10 

 per cent, below the pupils of the same age in the bet- 

 ter school, while the 10-year old Volksschule pupils 

 attain the same measure of success as the Vorschule 

 pupils a year younger. That, however, there is no 

 real equality in this relationship is shown by the two 

 other columns in which the percentage for the easier 

 tests (9 and 10 levels) and the harder ones (levels 11 

 and 12) are calculated separately. While, in the 

 easier tasks the Vorschule pupils, curiously enough, 

 rank a little below the Volksschule pupils of their 

 own age and 9 per cent, below the older pupils in 

 that school, the outcome is quite different when we 

 pass to the harder tasks (third column). These 

 tests which lie above the age-level of the subjects 

 are passed by the Vorschule pupils nearly twice as 

 well as by their mates of like age in the Volksschule, 



14 For many very important tests, as for instance, description of 

 the pictures, no results are at my disposal yet.
