Rewrite content of view field based on value
you can rewrite the output of a field using "Rewrite the output" option in views.

In your case, you might also need php code:
ex:

   $selectedValue=5; // this you can get from the replacement tokens easily

   // this array can be populated using some db query too.
   $selectedText=array('1'=&gt;'satisfactory','5'=&gt;'Very helpful');

   $selectedDisplayTitle=$selectedText[$selectedValue];
   return $selectedDisplayTitle;


Hope this helps.
