q2 i? Among 28 selected 12- and 13-year-old subjects, pass rates on the twelve-year tests ranged from 11 per cent (repetition of sentences) to 71 per cent (line suggestion). → Carl C. Brigham 1914 q2 i? The twelve-year-old group showed an average age difference of −1.38, suggesting the twelve-year tests were too difficult. → Carl C. Brigham 1914 (2)

q2 · i? · associational · r2

Analysis of how twenty 12- and eight 13-year-old selected subjects (all of American parentage, up to grade, not graded below average) passed the twelve-year tests; Table VI prints pass rates from 11% to 71%, and the article judges the sentence repetition and comprehension tests "too difficult."

"The repetition of the sentence of twenty-three syllables was undoubtedly too difficult. The comprehension of the two complex situations seemed to be too difficult, probably because the situations given in the standardization were quite foreign to the experience of the children tested."

For the thirty-two twelve-year-old children, the average mental-minus-chronological difference was −1.38 (M.V. 0.81), which the article reads as indicating the 12-year tests were too difficult, partly because no tests above twelve allow raising the score above the basal age.

"From the results shown in Table HI, it would seem that the 12-year tests were too difficult, since the average difference between the mental and chronological age of thirty-two chil- dren twelve years of age is —1.38 (M.V. 0.81)."
