144 PSYCHOLOGICAL METHODS OF TESTING INTELLIGENCE 



second-best the places 1, 2, 4, the third the places 2, 4, 2, etc. The 



3+1+1 1+2+4 



averages are for Pupil A-'g - = 1.67, for B - 3 = 2.33, 



2+4+2 

 for C K- 1 = 2.67. Hence, in the final or amalgamated series, 



o 



A receives the Rank-place 1, B Place 2, C Place 3. 



If we proceed in this manner we may, I think, ex- 

 pect that the method of amalgamated ranks can be 

 worked out into a systematized plan of procedure, as 

 has already been done with the method of age-levels. 



Not until we combine both these ideas can we hope 

 to master the whole field of intelligence testing. The 

 system of levels draws the great wave-lines of mental 

 development: the method of ranking sketches the 

 finer ripples within each level, and in such a manner 

 that the precise evaluation of the degree of intelli- 

 gence of the individual child shall be possible. At the 

 same time, the purely psychological analysis of the 

 behavior of the subject toward the test must not be 

 neglected, because it supplements the quantitative de- 

 termination of intelligence by making it possible to 

 ascertain the qualitative l coloring' of the intelligence 

 in the individual case.
