Rating metrics:
Outliers can be removed when calculating a mean average to dampen the effects of ratings outside the normal distribution. This figure is provided as the trimmed mean. A high standard deviation can be legitimate, but can sometimes indicate 'gaming' is occurring. Consider a simplified example* of an item receiving ratings of 100, 50, & 0. The mean average rating would be 50. However, ratings of 55, 50 & 45 could also result in the same average. The second average might be more trusted because there is more consensus around a particular rating (a lower deviation).
(*In practice, some albums can have several thousand ratings)
This album is rated in the top 1% of all albums on BestEverAlbums.com. This album has a Bayesian average rating of 79.7/100, a mean average of 79.5/100, and a trimmed mean (excluding outliers) of 80.3/100. The standard deviation for this album is 14.4.

Beautiful environment, unique experience, love it
Not only do I need this in my collection, I really need to listen to Grouper. Beautiful music. Will be in my top 10 of 2011 and hopefully be in my decade chart. Can't believe we are almost done with this decade. (Edited)
