A comparative study of 65 children, mostly tested at a school in Ann Arbor and a hospital social service department, classifying each child as below, at, or above chronological age on both tests. The article reports that "44.44 per cent give the same" classification and 55.56 per cent differ; no inferential test is reported.

"of the 65 cases: 29 or 44.44 per cent give the same "rough" classification. 36 or 55.56 per cent give different classification."

Related Claims¶

• The Healy Picture Completion test is easier than the Terman Binet: a child ranking at age level on the Healy will in all likelihood test below age on the Binet, especially children of lower mentality — related
• Binet IQ correlates insignificantly with Healy Picture Completion score (r = +.15 ± .082) among 65 children — related
• Binet IQ shows a negative, insignificant correlation with Healy Picture Completion time (r = -.05 ± .093) — related
