Summary

A condensed, streamlined version of the popular, widely usedUnderstandable Statistics,8/e, this text offers instructors an effective solution to teaching the essentials of statistics within a shorter time frame. Designed to help students overcome their apprehension about statistics,Understanding Basic Statistics,4/e is a thorough, accessible text that demonstrates the applicability of statistics in the real world. Student-friendly highlights of the Fourth Edition include solutions and key steps to odd-numbered problems, highlighted definitions, Expand Your Knowledge and Cumulative Review Problems, and a complete technology package with additional learning opportunities and skills-reinforcement exercises. Coverage of regressionappears early in this edition. Proceduresprovide a brief summary of the statistical methods introduced in each chapter section. Examples and Guided Exercises demonstrate each Procedure. Cumulative Review Problemsappear at the end of Chapters 3, 6, 9, and 11 and integrate concepts introduced in the previous three chapters. Guided Exercisesimmediately follow selected examples and provide an opportunity for students to explore new concepts. Worked-out solutions next to each exercise give students immediate reinforcement. Focus Points!at the beginning of each section introduce the topics to be covered. Data Highlights: Group Projectsat the end of each chapter simulate real-world working situations. Together students discuss topics, analyze data, and formulate a group response to questions posed in the exercise. Linking Concepts: Writing Projectschallenge students to craft an essay response to questions that apply statistical concepts to real life situations.
