Zusatztext While there are numerous texts on the market with the same goal! this text takes a practical and effective approach to engaging students with a topic that! as the author notes! they are most likely not that interested in learning. The text accomplishes this goal quite well. ? It is written in a very straightforward and understandable manner that fits its intended audience quite well. ? Given that there are dozens of introductory statistics texts on the market. it has become exceedingly difficult to create one that can be truly differentiated from the rest. However! in this case! the author appears to have succeeded. This is accomplished in large part by taking a down-to-earth! almost intuitive! approach to the material which is both refreshing and welcome. -Tom Page! The American Statistician! August 2011In this excellent textbook Professor Leekley takes the reader! as if they were his students! through every detail of examples! working all steps with great patience. This generous approach is even extended to explaining how mathematical and statistical notation and symbols are read; a very rare and valuable education. ? This book is highly recommended as a textbook for business statistics and it can also be used as a manual for self-study.-Journal of the Royal Statistical Society: Series A! July 2011For the mathematician! this text does an outstanding job of integrating things on the mathematical level. ? This is one of the few texts to try to make plausible the complex formula for two-sample t degrees of freedom when we do not assume the two variances are equal. ?
