Mark Harmon is a university instructor of business statistics and began doing statistical work as an Internet marketer of his own company. He wanted to know if advertising campaigns that he was running were really working. Mark pulled out his 3 and ½-inch thick statistics book from his old MBA statistics course. That turned out to be no help at all so he began to write a statistics manual for himself to use in Excel. To make a long story short, Mark Harmon's little manual evolved into a 10-book series called the Excel Master Series. The series is aimed at simplifying graduate-level statistics and demonstrating how to perform all statistical techniques in Excel. The books and ebooks of this series have been widely sold and Mark has many customers in over 30 countries in the world. Any customer who purchases any of the books in the series is entitled to free statistical consultation. Mark has since helped many graduate students and professionals with some of the most unusual statistical problems that can be imagined. He really enjoys doing that.Mark Harmon is a natural teacher having spent nearly five years in Austria and Czech Republic instructing undergraduate, graduate, and MBA students marketing and finance courses.
