Title: 12th ed. has problems
Review: The 12th edition of this book contains a surprising number of errors. I am currently using this book for a statistics course in an MBA program. We are twelve chapters into the book now and in most every chapter I have found a mistake; more often than not there are multiple mistakes. What is worse is that the majority of the mistakes are in the practice problems which are where the student learns to apply the skills. This serves to create confusion and frustration on the student's part. Some of the mistakes are sloppy editing while others more significant are providing wrong information. The editors need to take another look at this book and the authors should also take note.
Is the review positive or negative?
