Opis

Written as a supplemental text for an introductory or intermediate statistics course, this book is organized along the lines of many popular statistics texts. The chapters provide a good conceptual understanding of basic statistics and include exercises that use S-PLUS simulation programs. Each chapter lists a set of objectives and a summary. The book offers a rich insight into how probability has shaped statistical procedures in the behavioral sciences, as well as a brief history behind the creation of various statistics. Computational skills are kept to a minimum by including S-PLUS programs that run the exercises in the chapters. Students are not required to master the writing of S-PLUS programs, but explanations of how the programs work and program output are included in each chapter. S-PLUS is an advanced statistical package that has an extensive library of functions, which offer flexibility in writing customized routines. The S-PLUS functions provide the capability of programming object and dialog windows, which are commonly used in Windows software applications. The S-PLUS program also contains pull-down menus for the statistical analysis of data. A ZIP file containing programs that work in S-PLUS 6.2 for use with this book is available for download from http: //www.psypress.com/resources/9780805836233.zip - please note that these scripts will only run in S-PLUS 6.2 and not later versions due to changes in the programming language syntax.

Recenzje

"A particularly useful feature of each chapter is the summary, which, in a succinct fashion, lists the concepts to be mastered."
—CHOICE

"With the inclusion of S-Plus script files, their book [Schumacker/Akers] is intended to help students understand the statistical concepts covered in the classroom and in the primary textbook, as well as to introduce them to the S-Plus statistical software".
—The American Statistician

"This book is a beginning statistics text that contains many S-Plus routines which have been supplied on an accompanying CD. The book is a potential vehicle for learning S-Plus by means of the hands-on approach of understanding the many existing routines."
—Journal of Mathematics Psychology
