q2 i? In the long run the scale graded accurately for ages 7 through 11, with average age differences near zero for those years. → Carl C. Brigham 1914 q2 i? The summary conclusion states measurement with at least 96 per cent efficiency for ages seven to eleven. → Carl C. Brigham 1914 (2)

q2 · i? · associational · r2

Analysis of 270 examined cases aged six to thirteen, classified by the method of age differences; Table III prints average differences of +.05 to −.70 for ages 7–11, with the article concluding the scale "graded accurately in the long run for the ages of 7, 8, 9, 10 and 11 years."

"From these results the conclusion may be safely drawn that the Binet-Simon scale graded accurately in the long run for the ages of 7, 8, 9, 10 and 11 years."

The article's summary states the scale measured intelligence development from seven to eleven years "with at least 96 per cent, efficiency" under the conditions of the experiment; the 96 per cent figure is the article's own printed value, not an effect size.

"The Binet-Simon scale, as now standardized, was found to measure various stages reached in the development of the intelligence of the children examined, from seven to eleven years of age, with at least 96 per cent, efficiency."

Related Claims¶

• The Binet-Simon scale accurately graded fairly minute individual differences in mental ability within same-age groups, as validated against teacher and principal judgments — related
• The personal equation of the experimenters never amounted to more than one-third of the average mean variation, too small to be considered significant — related
• Exceptional Binet-Simon test outcomes were rare (4 per cent) and mostly attributable to error in adult judgments rather than the scale — related
• The twelve-year tests of the Binet-Simon scale were unsatisfactory, with several individual tests too difficult for the children tested — related
• Psychology has helped develop methods for determining school-system efficiency, including pedagogical retardation statistics and measurement scales — related
• The study's conclusions rest on only sixty-five individually tested unretarded cases, limiting generalization — related
• Taylor's Sheffield study suggests the Binet scale is broadly suitable for English children, though tests for ages 6 and 7 seem too easy and tests above 11 seem unsatisfactory. — related
• The Binet scale can be understood and applied by the average teacher or school principal as readily as current pedagogical tests — related
• The Binet-Simon scale is a valuable diagnostic tool for classifying defective children when used by a trained examiner but dangerous in untrained hands — related
