The relationships, if any, between this ability and sex, intelligence quotient, chronological age, mental age, and grade could then be statistically determined. PROCEDURE After a preliminary study, to aid in developing the instrument to measure quantitative judgment, a total of 704 public school children in the intermediate grades were tested on aspects of quantitative judgment with the refined instrument. Two other instruments were also administered to each child tested: (1) The Kuhlmann-Anderson Intelligence Tests, Seventh Edition, and (2) Functional Evaluation in mathematics, Test 1. Chronological and mental ages were also recorded. Means and standard deviations were computed for the Test of Quantitative Judgment developed for this study. Intercorrelations were statistically determined among the five measures--quantitative judgment, intelligence quotient, arithmetic understanding, chronological age and mental age--at each grade level for girls, boys and totals. The reliability and validity were computed for the Test of Quantitative Judgment developed by this writer. Statistical validity was determined by entering Chung-Teh Fans Table with the upper and lower 27 per cent passing, from which was obtained the validity index of each item. Reliability of the test was determined by using the Kuder-Richardson formula Number 20 and also by test re-test of a representative sample of the population used. The data were analyzed, means and standard deviations determined, and tests of significance applied. The means and standard deviations of the test scores on the Test of Quantitative Judgment and the reliability of the test by grade are shown in Table I on the next page. [TRUNCATED] / 2999-01-01
