Subclaims¶

q2 i? The Pearson correlation between mental and physical composite ranks is .21 (P.E. .064) at fourteen and .33 (P.E. .060) at fifteen years, low enough that children can be roughly distinguished into five groups differing in mental and manual ability profiles. → Woolley 1915

Evidence¶

Woolley 1915¶

Woolley, Helen Thompson. (1915). A new scale of mental and physical measurements for adolescents, and some of its uses. The Journal of Educational Psychology, 6(9), 521-550. https://doi.org/10.1037/h0075644

q2 · i? · associational · r1

Correlational analysis of the fourteen- and fifteen-year composite scores of the working-child sample, showing mental and manual ability correspond only loosely. The authors use this to distinguish five rough groups: poor, medium, and good in both, plus high-manual/low-mental and high-mental/low-manual groups.

"There is a positive correlation between rank in mental tests and rank in physical tests, but it is small. The Pearson co-efficient is .21 P. E. .064 at fourteen and .33 P. E. .060 at 15 years."

Discussion¶

Learner Variables¶

• Physical Well-Being — predictor: learners who differ on it differ in outcomes
