A median mental age method of weighting and scaling mental tests

Abstract

"The present article describes a different procedure in weighting tests and in scale construction. The chief thing in the method consists simply of using an age norm for each trial in each test in the group-test battery, instead of only for the summation or total score on the battery. Instead of determining the average total score that children at each age make on the battery of tests, we have determined first the average age of the children that pass just one trial, just two trials, etc., of each test." The several steps in the development of the scale of 35 tests with this method of weighting the scores are critically analyzed. Eight noteworthy outstanding traits of the tests with the present method of weighting and scoring are summarized at the end of the article. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
