*It seems likely that any product with a 1-start rating only has one (or a small number of) reviews as well.  Usually a product has ''some'' redeeming value that someone will find useful.

**Usually the developer or at least a friend will provide a positive rating and review, though the issue of self rating isn't specifically addressed by this comic. Still, if 3 users give it a 1-star review, but the developer has access to at least 2 accounts that can give a 5-star rating, you still result in 13/25 rating, or two-and-a-half stars, which is why that star rating would be "crap".--[[User:DanB|DanB]] ([[User talk:DanB|talk]]) 16:31, 22 August 2012 (UTC)

*** Agreed.  If there's only one review, it most likely comes from the supplier / author / producer, and in that case it's going to be a five star rating.  From that perspective, the only way to get a bad _average_ review is if there are many bad reviews.  As an example, consider a product with five reviews: 5, 2, 2, 1, 3.  The average is 2.6, and depending on the implementation this might be shown as "two and half stars" or "three stars".  If you take out the 5, you get an average of 2.  Consider the case of two reviews, 5 and 1.  The 5 is from the author and the 1 is from a real user.  Average is 3.  Considering the other cases (5 and 2, 5 and 3, 5 and 4) the averges are 3.5, 4, 4.5.  As you can see, anything below 3.5 is crap (the 1 and 2 from real users) and 4 and 4.5 are indeed ok (3 and 4 from the real user).  As the number of "real" reviews increases, the average will tend towards the actual average perception from users (law of large numbers), and there is ''no way'' to get a 5 on average because of the fact that when dealing with subjective evaluation, ''someone'' is going to think the product is crap, therefore a five star rating is the product of a single review from the author.  [[User:Mem|mem]] ([[User talk:Mem|talk]]) 20:56, 22 August 2012 (UTC)
