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.
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?
