A brief version of Gravetter and Wallnau's proven bestseller, ESSENTIALS OF STATISTICS FOR THE BEHAVIORAL SCIENCES, 8e delivers straightforward instruction, unrivaled accuracy, built-in learning aids, and a wealth of real-world examples and illustrations. The authors take time to explain statistical procedures so that students can go beyond memorizing formulas and begin gaining a conceptual understanding of statistics. By skillfully integrating applications that reinforce concepts, they also ensure that even students with a weak background in mathematics can fully understand statistics. Illustrating how having an understanding of statistical procedures will help students comprehend published findings, the text leads readers to become savvy consumers of information. In addition, a complete supplements package supports instructors with class preparation and testing, helping maximize course success.
