(Off-topic) The top rated review of this book is from Peter Norvig. He states "For most books, the review is a bell-shaped curve of star ratings". However, as a habitual window-shopper of books in Amazon, I have rarely come across rating distributions which look like normal. In my experience, 2 and 3 ratings are much less common than 5, 4 or 1.
- kidnoodle 11y agoI have a blog post I've never quite finished writing, walking through some analysis of the 34,686,770 Amazon reviews in the Stanford SNAP dataset (https://snap.stanford.edu/data/web-Amazon.html https://snap.stanford.edu/data/web-Amazon.html, but there's a newer and better one at http://jmcauley.ucsd.edu/data/amazon/ http://jmcauley.ucsd.edu/data/amazon/). Somewhat surprisingly, the median review score is 5, and if you look at median scores for products, the skew is very much left. So, the data pretty much backs up your observation!
