q2 · i? · associational · r1

Comparison of upper-four and lower-four scholarship groups within eight boys who entered high school in September 1910 and graduated in June 1914 (Chart VII), the largest same-age same-class group with complete measurements. The higher-scholarship half "averaged taller" all four years.

"Throughout the four years the half which ranked higher in scholarship also averaged taller. And, except in the Junior year, they also averaged heavier."

Discussion¶

Related Claims¶

• Among boys of the same age, those one year above normal grade average both heavier and taller than boys of normal grade, and in some cases boys one year below normal also average heavier and taller — 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
• Groups one year ahead of normal grade increase more rapidly in both weight and height than normal groups of the same age, with one exception — related
• 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
• Group averages suggest a positive relation between weight and scholarship in the elementary grades, but the relation in high school is uncertain — a broader claim this one bears on
• Most high-school students made rapid or normal elementary progress, yet most fail in some high-school work, and schools appear better fitted for girls than for boys — related
