Subclaims¶

q2 i1 The product-moment correlation between Binet IQ and Healy Picture Completion score is r = +.15 ± .082, which the author describes as insignificant because the probable error is twice as large as r. → E. B. Skaggs 1920

Evidence¶

E. B. Skaggs 1920¶

E. B. Skaggs. (1920). A Comparison of Results Obtained by the Terman Binet Tests and the Healy Picture Completion Test. The Journal of Educational Psychology. https://doi.org/10.1037/h0076088

q2 · i1 · associational · r1

A product-moment correlation computed across the same 65 children tested by both instruments. The article reports the coefficient as "insignificant, the probable error being twice as large as r." The printed effect size r = .15 corresponds to a small correlation.

"The correlation between Binet I.Q. and Healy Score: r = + .15± 082."

Discussion¶

Learner Variables¶

• General Cognitive Ability — predictor: learners who differ on it differ in outcomes

Related Claims¶

• The Terman Binet and Healy Picture Completion tests give extremely different classifications of the same children, with only 44.44 per cent of 65 cases receiving the same rough classification — related
• Binet IQ shows a negative, insignificant correlation with Healy Picture Completion time (r = -.05 ± .093) — related
• 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
