Statistical Reasoning for the Behavioral SciencesAccording to Richard Shavelson, the goal of any good statistics book is for readers not only to learn the meaning of statistical concepts but also to be able to use these concepts to solve problems. This new, revised edition of Statistical Reasoning is written with a two-pronged objective: conceptual and procedural knowledge of statistics. Extensive use of verbal as well as visual exposition, and an uncommonly wide use of figures that parallel what is being explained in the text, aids the learning process and provides, in the author's words, a "motion picture of the concepts at work." In addition, the book motivates the study of statistics with research design in areas such as psychology, education, and sociology and illustrates the usefulness of statistics for research in these fields. |
