Subclaims¶

q2 i? Regression prediction of height six years later yields PE of estimate of 2.98 cm for 12-year-old boys and 2.58 cm for 12-year-old girls, and 2.09 cm and 2.81 cm for the older group. → Bird T. Baldwin 1922

q2 · i? · associational · r2

Regression-based prediction analysis of the Iowa height data using the Pearson correlation method. The author reports "The PE of estimate on any individual case in these two groups" as 2.98 cm for boys and 2.58 cm for girls predicted from age 6.

"The PE of estimate on any individual case in these two groups, when the height of 12 year old boys is predicted from the height at 6, is found to be 2.98 cm., and for the 12 year old girls 2.58 cm."
