Description¶
The article's method is to first establish constancy of conditions, then compare standings. The authors write that "in order to make our investigations as constant as possible it was necessary that we should select from the many students a certain group which had passed through the same conditions in respect to time of studying the subjects investigated, years of schooling, instructors, etc." This makes grade-based group comparisons interpretable as reflecting pupil ability rather than differing instruction.
Accounts¶
- Control instructional conditions by studying a cohort with identical instructors, subjects and years before comparing grade-based ability correlations: The article's method is to first establish constancy of conditions, then compare standings.

(L. E. Frailey et al. (1912))
Claims¶
- Pupil standing in one school subject correlates with standing in other subjects, most perfectly among the highest- and lowest-ranked pupils and least among pupils of medium ability [+M]
- Pupil standing in one subject is more stable across successive school years than across subjects of different nature, with 13 of 32 pupils in the same group for all four years of English [+M]
