q2 i? Graphs of average percentile ranks against school grade show a small positive correlation for physical tests and a large positive correlation for mental tests, with fifth- and eighth-grade curves crossing only over a small portion of their extent. → 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 · r2

Graphical and tabular analysis (Graphs 1 to 8 and tables of averages of percentile ranks by type of school, sex, and school grade) of fourteen- and fifteen-year-old working children, relating composite mental and physical percentile averages to the school grade each child had completed.

"The graphs for the averages in physical tests show a small positive correlation with school grade, and those for the mental tests a large positive correlation, so large that the graphs for fifth and eighth grade children cross for only a small portion of their extent."

Discussion¶

Learner Variables¶

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