title: Get Average Value of a Field
body: <p>I'm using integer fields for a review system in Drupal. </p>
  
  <p>I would like to add up all the values of a specific integer field (globally), and then divide that by the number of fields to get the average. I can get the total integer value of one node, but I want to get the value of all the nodes with a specific node reference. </p>
  
  <p>I've tried looking around for solutions using computed fields and views php, but I have limited php skills.</p>
  
  <p>Any help would be much appreciated.
  Thanks</p>
