Economics Professor Prem Mann is preparing the eighth edition of his "Introductory Statistics" book, scheduled to be published by the end of this year. Mann's books are used in many countries and "Introductory Statistics" is among the best-selling introductory statistics books. The book's earliest editions have been translated into the Chinese, Portuguese and Serbian languages. Mann has also authored "Statistics Using Technology and Statistics for Business and Economics," which was translated into Chinese. He co-authored (with Mikael J. Harry, Ofelia C. De Hodgins, Richard L Hulbert, and Christopher J. Lacke) the book, "Practitioner's Guide to Statistics and Lean Six Sigma for Process Improvements," published in 2010.
