Who really knows what drives Amazon’s decisions about how books should be categorized? Not me. The first edition of How to Measure Anything was categorized on Amazon as “math for business” and it was virtually always able to hold the #1 rank in that category for the three years since its publication.
Now the second edition has been categorized, instead, as “statistics”. I was concerned that the new category might exclude more readers; however, it does not seem to have had that effect. Statistics is also a more competitive category. But my concerns seemed to be misplaced. It has held the #1 rank in statistics almost every day since its release and the overall Amazon rank has also been consistently better. Perhaps the new category will help it reach more people after all. What was I thinking questioning Amazon’s judgment, anyway?
