Entry 447 annotates Woolley's 1916 Survey article: she "Applied point scale to 18 year-old industrial workers" and "25.5% were found feeble-minded." The annotation prints the percentage descriptively; no effect size or test statistic is given.
"Applied point scale to 18 year-old industrial workers. 25.5% were found feeble-minded. Advises change in the definition of feeble-mindedness, so that the tests should yield a proportion of mental deficiency more in harmony with the common sense opinion of legislators."
