Unit values from 100 first-year normal school girls are strikingly like those obtained from the 25 advanced university subjects, suggesting maturity differences may not change relative difficulty proportions.¶

Dr. Butterworth administered the same test the following winter to "one hundred first year normal school girls as a mass test", using stop-watch timing as each finished a red-line-delimited unit; the computed unit percentages closely matched the university values (e.g., unit 1: 12.8 in both).

"The values last secured from the hundred girls are strikingly like those obtained by more accurate methods from the twenty-five more advanced subjects in the University of Iowa."

• The reported difficulty values are based on scholastically advanced adults, and whether the proportions would hold for less mature subjects remains an open question. — related
