Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
First of all, i purchased this for my daughter who is a very big Friends fan. The cards are not cut the same and very difficult to pick up off each pile. We found some questions that were incorrect based on the episode the card was claiming when it was a different episode. We found several typos on the cards and incorrect grammar.
