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 tracks can have several thousand ratings)
This track is rated in the top 1% of all tracks on BestEverAlbums.com. This track has a Bayesian average rating of 87.0/100, a mean average of 86.5/100, and a trimmed mean (excluding outliers) of 87.2/100. The standard deviation for this track is 10.2.

Honestly one of my absolute Zeppelin favourites. Definetly in the top 5. It is far too underrated and the bass line is just killer. (Edited)

Yet another example of a song mostly made by the horribly underrated John Paul Jones' brilliant bass line. (Edited)

On of Zep's greatest songs ever, thanks in no small part to John Paul Jones' superb contributions on bass. (Edited)
Fantastic song, one of my favs on the record. (Edited)
Definitely one of Zeppelin's most underrated songs. (Edited)
