Subclaims¶

q2 i? Because most cases were referred for school failure or truancy, many cases fell below their chronological age on both tests and few measured up to normal. → Zimmerman 1914

The author's interpretation of the Chart I data: the sample was dominated by children referred by schools and the Bureau of Attendance for unsatisfactory progress or truancy, skewing ratings below chronological age.

"Bearing this in mind one will understand why so many cases fall below their chronological age in both of the tests and also why so few cases measure up to normal."

• The Binet-Simon and Yerkes Point Scale ratings of children run parallel and are practically identical up to age ten — related
• Yerkes-Bridges coefficients of intelligence of 1.20 or more are attained by very different percentages of children at successive ages (34.5% at ages 4-5 down to 0% at ages 16-17 and 18-on), so they do not represent the same degree of brightness at all ages. — related
