q2 · i? · associational · r1

Study of 24 Geneva pupils, one bright and one dull boy and girl from each of the six primary grades, each tested with all questions of the 1908 scale; results were not tabulated, and the reviewer reports some correlation with teachers' estimates of bright and dull.

"The author finds the scale too easy at the bottom and too hard at the top (as does Terman in the present issue). The bright pupils do better than the dull ones (57% to 43%), and the boys make a slightly better showing than the girls (53% to 47%)."
