Subclaims¶

q2 i? Among 600 students, over half had discrepancies of less than 20 percentile points between Alpha intelligence rating and first-semester scholarship percentile. → Stone 1924 q2 i? 62 cases had discrepancies of 50 percentile points or over, and 53 of them remained in college during the second semester. → Stone 1924 (2)

q2 · i? · associational · r1

Observational computation for the Dartmouth class of 1924: scholarship averages and Alpha intelligence ratings were converted to percentiles and the per-student difference taken as the discrepancy measure. The article reports that "over half of the class had discrepancies of less than 20 per cent."

"On the basis of such computations, including 600 cases, it was found that over half of the class had discrepancies of less than 20 per cent, or 20 points on the percentile rating."

q2 · i? · associational · r1

The same percentile-discrepancy computation identified 62 extreme cases; the article notes that "53 re- mained in college during the second semester," and these men became the discrepancy group for follow-up testing.

"Of the 62 cases with discrepancies of 50 per cent or over, 53 re- mained in college during the second semester."
