Summary:

"The beginner in experimentation too often finds himself supplied with a pair of elaborate mechanisms. In the one hand is a mass of data demanding simplification and interpretation, while in the other is a complex statistical methodology said to be necessary to research. How shall the two be geared together? Since the data can be only inefficiently utilized without statistical method, and since method is futile until applied to data, it seems strange that greater effort has not been made to unite the two. For those of some experience there are adequate texts and journal articles. It is the novice to whose needs this book is directed. It is hoped that he may be furnished with a smoothly working combination of experimental data and statistical method. The arrangement of the material in this text on statistics is not so much logical as developmental. The easiest ideas are put first, and only one new concept is presented at a time. The experienced reader will often feel a sense of inadequacy. It is believed that this will disappear as he continues, and that the inexperienced will be inducted with a minimum of difficulty. Numerous examples form an indispensable part of the presentation. In most of them the statistical method, with its meaning, is emphasized, the necessary drudgery of calculation being reduced to the lowest level. In this edition the text has been largely rewritten, and the scope has been widened as follows: (i) greater emphasis has been placed on the theoretical conditions in which the various statistical methods have validity, and concurrently (ii) on the conduct of the experiment so as to incorporate in the data the information desired; (iii) estimates and fiducial statements have been brought into equal prominence with tests of hypotheses; (iv) there is increased reliance on experimental samplings to exemplify distribution theory; (v) the treatment of correlation and of experimental designs has been expanded; and (vi) the methods for disproportionate subclass numbers have been extended to include all those necessary for ordinary needs"--Preface.
