Intro Stats

The short, teachable chapters and approachable, colloquial style of Intro Stats has made it the most successful first edition Statistics text. Now a hallmark feature, Intro Stats teaches readers how to think statistically, show proper application of techniques, and tell others what they have learned. What Can Go Wrong? sections in each chapter give students the tools to detect statistical errors and debunk misuses of statistics, whether intentional or not.
