An absolute intelligence scale: A study in method

Abstract

Investigates the value of a series of group intelligence tests. School children aged six to 17 yrs were given nine tests and norms were secured for the age range six to 13 yrs. Point scale norms for individual tests and point values for scores were determined. Out of the nine tests, the opposites test exhibited a higher degree of discriminative capacity and greater weight than the cancellation test. The different tests had weight directly in proportion to their discriminative value which is its capacity for bringing out individual differences in intelligence. Concludes that the absolute intelligence scale (the nine tests combined) represented the normal growth in absolute intelligence from the age of six and a half to 13.5 yrs. Compares the I.Q. obtained by group testing to that obtained by individual tests. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
