The focus of this book is the experimental study of the abilities of high school pupils and how they can be analyzed and predicted. It includes a range of research-based techniques that can be used to assess students' abilities and provide guidance on how they can improve. The book is suitable for educators and parents interested in helping students achieve their full potential.
This volume constitutes a radical revision and extension of the author's 1938 Tables. Herein is an extensive table of normal probability functions. 3-point interpolation coefficients are given with 4 figure arguments. These coefficients are compensatorily rounded off to five figures. A similar rounding off to seven figures of 4-point coefficients has been made. Truman Kelley's method for normalizing variance ratios, which he presents together with tables facilitating the process, is of particular importance for experimental scientists.
