This worktext encourages hands-on exploration of statistical concepts so that students take an active part in the learning process. With its strong emphasis on data analysis, this book seeks to make students better consumers of statistics and to give them the skills to design and execute experiments in an undergraduate research class. Statistical concepts are presented economically and immediately reinforced with activities—to be done in small groups or individually—that make the concepts clear and vivid. The TI graphing calculator, although not required, is integrated as an easy-to-use, portable tool that helps students to see statistical methods and models in action. A comprehensive Instructor's Resource Manual, developed by the authors, gives extensive support and guidance for teaching interactively.
