Comparative validity of primary intelligence tests

Abstract

One hundred first grade children were given the Stanford-Binet, Haggerty Delta I, Pressey Primary, Pintner-Cunningham Primary, Detroit First Grade, Otis Primary, Kingsbury Primary, and Rhode Island Intelligence Tests. A statistical study was made to determine their comparative validity according to such standards as correlations and deviations between the mental age and intelligence quotients as determined by any one or pair of group tests and the Stanford-Binet or the seven group tests as a whole, the nearness to a normal distribution and central tendencies, and agreement with the criteria in the three fold sectioning. Of the seven group tests used no one was found to be more valid than the others in every respect; in fact, those that stood high according to one test very often stood very low according to one test very often stood very low according to other tests. However, taking the results as a whole, it was concluded that for this particular grade, the comparative validity of the seven group tests is in the order in which they are named above.
