Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Correlations between height rankings at 6 or 9 years of age and 6 years later range from +0.735 to +0.944 for 125 boys and girls, indicating stable relative position. → Bird T. Baldwin 1922

Correlational analysis of consecutive height measurements in the Iowa longitudinal growth-curve series. The author reports that "the coefficients of correlation for 125 boys and girls at 6 or 9 years of age and 6 years later range from +0.735 to +0.944."
"Using the Pearson method, the coefficients of correlation for 125 boys and girls at 6 or 9 years of age and 6 years later range from +0.735 to +0.944."

Related Claims¶
- Average-type children's percentage of final height attained by age 7 supports prediction of ultimate stature (70.3% for boys, 74.2% for girls) — related
- Height at age 12 can be predicted from height at age 6 with a probable error of estimate of 2.98 cm for boys and 2.58 cm for girls — related
- Growth measurements at age ten predict stature at sixteen within about 2.5 centimeters and IQ over the same period within 6.3 points — related
- Cross-sectional measurements of children of the same age may yield spurious growth facts because of great individual differences — related
- Coefficients of variability for physical traits tend to decrease from ages seven to seventeen and are generally higher in boys than in girls, per the review of Baldwin's growth study — related
