The author's own tally of problem mentions across the searched 1921 periodical issues, reported in the summary section. The counts are descriptive frequencies; no effect size is reported, so impact is null.

"it is only necessary to count the references under each heading to get an idea of the relative frequencies of the problems thus grouped: Mental Tests 16; Curriculum Studies 15; Administration and Supervision 11; Educational Tests 9; Learning Studies 8; Rating Scales 3; Statistical Devices 2."
