<p>Portraying data graphically certainly contributes toward a clearer and more penetrative understanding of data and also makes sophisticated statistical data analyses more marketable. This realization has emerged from many years of experience in teaching students, in research, and especially from e

✦ Synopsis
Springer, 1986. — 321 p. — ISBN: 1461293715, 9781461293712, e-ISBN: 9781461249504.
With 180 Graphical Representations.
This book, therefore, attempts to give a sound overview of most of the wellknown and widely used methods of analyzing and portraying data graph ically. Throughout the book the emphasis is on exploratory techniques. Realizing the futility of presenting these methods without the necessary computer programs to actually perform them, we endeavored to provide working computer programs in almost every case. Graphic representations are illustrated throughout by making use of reallife data. Two such data sets are frequently used throughout the text. In realizing the aims set out above we avoided intricate theoretical derivations and explanations but we nevertheless are convinced that this book will be of inestimable value even to a trained statistician.
