A comparison of the point scale and the group method of measuring mental ability
Within the past decade great interest has arisen in the measurement of mental ability. As a result a vast deal of literatures has been written upon this subject. Psychologists have suggested and secured norms for many tests, most of which, or perhaps all of which, are based more or less upon the original Binet-Simon tests. However, this study does not propose either to list or review the history of such mental tests. The one problem of interest, and the problem to which we shall adhere strictly, is to discover the correlation which exists between the Group Test of Mental Ability as worked out and tested by W. H. Pyle of the University of Missouri, and the Individual Tests, otherwise known as The Point Scale Tests as worked out and tested by Robert M. Yerkes, James W. Bridges and Rose S. Hardwick, each of the Psychopathic Hospital, Boston. a thorough explanation of each of these two tests is given in Appendices I and II of this study.
