520			_a"This book attempts to present to the student in psychology, education, sociology, and the behavioral sciences, some of the newer developments in statistical analysis, particularly with respect to small-sample theory, as they relate to problems of research and experimentation in these fields. I have assumed that the reader will have a working knowledge of algebra and that he will be familiar with the elementary notions of statistical methods as taught in the usual introductory course in applied statistics. Nothing more in the way of previous mathematical training is required for an understanding of the material presented. A number of hypothetical sets of data are interspersed with the results of actual experiments. I have attempted to arrange the examples at the end of each chapter so that some illustrate by fairly easy computations the kinds of analysis described in the text. Some problems requiring more prolonged calculations have also been included. These examples are in all cases modeled after the methods presented in the chapters. I have also included in the examples at various times, a brief discussion of a particular point which the example has been designed to illustrate. I trust these discussions will not be overlooked by the casual reader. Answers to all examples are given in the appendix. It will be obvious to the careful reader, but it is a pleasure to acknowledge it here also, that I owe much to the various publications of R. A. Fisher, Frank Yates, John Wishart, M. S. Bartlett, G. W. Snedecor, W. G. Cochran, and others. I have tried to acknowledge these sources at the appropriate places throughout the text." —Preface
