Entity Average Rating I have Player (Entity) which is referenced on a Match (Content Type).

Now I'd like to Rate (from 0 to 10) the player for every match and get the average rating, can someone point me to the right solution.
You can make a View and use the Views Aggregator Plus or Views Calc.

From Views Calc module page:


  This module adds simple calculations to a views table.
  
  You can SUM, AVERAGE, COUNT, MIN, MAX, or AVG selected columns. A plug
  in theme makes the view look more spreadsheet-like (right justifies
  numeric fields, shades calculated columns and rows, and underlines
  calculated rows).


You can found some screenshots here: How can I show average votes of fivestar nodes?
