Subclaims¶

q2 i? When emphasis is placed on averages representing larger numbers of measurements, a positive relation between weight and scholarship appears in the elementary grades, while the high-school relation is uncertain. → Stewart 1917

q2 · i? · associational · r1

Observational analysis of group averages from the 583-weight distribution by age and grade (Chart I). The author emphasizes averages based on larger numbers of measurements, finding "a positive relation between weight and scholarship in the elementary grades."

"When this is done, there appears to be a positive relation between weight and scholarship in the elementary grades, but the relation in high school is uncertain."

Discussion¶

Related Claims¶

• When individual growth-increment curves are correlated with scholarship without reference to body size or stage of development, no decided relation between scholarship and physical growth appears — related
• When body size at fourteen and period of rapid growth are considered, heavy or tall early developers rank better in scholarship than late developers, and light late developers rank better than light early or medium developers — related
• In a same-age, same-class group of eight boys followed through high school, the higher-scholarship half averaged taller in all four years and heavier in all years except the junior year — a narrower finding that bears on this claim
