# Statistics for the Behavioral Sciences

Cengage Learning, 2009 - Mathematics - 783 pages
By far the best-selling introduction to statistics for students in the behavioral and social sciences, this text continues to offer straightforward instruction, accuracy, built-in learning aids, and real-world examples. The goal of STATISTICS FOR THE BEHAVIORAL SCIENCES, 8th Edition is to not only teach the methods of statistics, but also to convey the basic principles of objectivity and logic that are essential for science and valuable in everyday life. Authors Frederick Gravetter and Larry Wallnau help students understand statistical procedures through a conceptual context that explains why the procedures were developed and when they should be used. Students have numerous opportunities to practice statistical techniques through Learning Checks, examples, step-by-step Demonstrations, and problems. A strong ancillary package includes PowerLecture(tm), which contains lecture slides, JoinIn(tm) Student Response System content, and a computerized test bank; Enhanced WebAssign, a complete and easy-to-use homework management system; WebTutor(tm); an Instructor's Manual/TestBank, plus other online and print resources.

This is one of the best textbooks in the field, every edition of it. It is not intended to be a quickie book for those who just want the superficial. It is one of the books to keep as a reference and refer back to as education progresses. It is dense and goes into a lot of detail, more than is needed in most first semester psychological statistics classes. Some of the negative comments indicate the lack of understanding many students have with statistics. The range actually has two forms, one in which the upper limit of the high score and lower limit of the lower score are subtracted. Rather than go into a discussion of upper and lower limits, many textbooks say high score minus low score plus one (which gives the same answer). This is the range of scores in statistical analysis. More recently some authors have been giving the arithmetic range, which is highest minus lowest. Some of the other negative comments are likewise invalid.
