I am trying to compare different survey questions against each other to show greatest improvement of scores. Here is a description of the case:
I have customer service questions that I am trying to compare month to month improvement to. My issue is that certain questions have scored relatively high and others very low. Theoretically, the low scoring questions have a greater opportunity for improvement than the higher scoring ones. (Example, one question has scored a 65% where the best score of another question is 85%. So it is easier for the 65% question to improve than the 85% question.) Is there a way to normalize/standardize the scores where I can show which improvement is the greater achievement?
