q2 · i? · review · r3

The reviewer compares age rankings of each 1911 test compiled from Binet, Levistre and More, Johnston, Goddard's Vineland data, Bobertag, and Terman and Childs, using the criterion that a test was properly ranked when "75% of the children of that age were able to pass it."

"An inspection of the table shows that in spite of many differences in the rankings of individual questions there is? a surprising agree- ment in the results of the different investigators. This is the more striking in view of the widely separated communities in which the tests were made."
