I read a story in the news today about the average rating on the internet being a 4.3 out of 5. Spoke with the kids about the meaning of a school where the average grade is 8/10 vs. one in which it is 5/10. Maybe the tests are tougher, maybe the children study less, maybe the teachers are worst... Same for a city in which the average restaurant rating is 4.5/5 vs. one in which it is 2/5. Maybe the restaurants are worst, maybe the citizens are all foodies, maybe they are just more critical...
Take away? When you see a 4.3 rating on Amazon (or Yelp), know that is an "average" rating. For something to be really good, the rating should be 4.5 or higher. And, of course, a 3 is pretty bad.
