Abstract
THIS volume by an educationist should be of great service to those who use statistical methods in any field, since it provides a summary of nearly all, if not all, the methods which have been proposed for measuring relationship. This seems likely to be its chief use, but it includes also a discussion of frequency odistributions and of Pearson's set of curves, with chapters on index-numbers and other special applications. The study begins with data already collected, but the introductory chapters outline the principles of tabulation and graphical representation. Although problems are suggested in several chapters, the book can scarcely be regarded as a text-book for beginners, being very condensed in many parts, with few worked examples, but rather is a critical survey. In the treatment of correlation much use is made of a symbol for Ji -r2 as “coefficient of alienation.” Appendices supply a list of symbols used, a bibliography-which is not up-to-date as regards editions of books-and an extended table of deviates of the normal curve. The index is small but useful.
