I asked users to complete a likert survey (1-5) at the start of an activity, and conclusion of the activity. What is the best manner to show the rate of change/difference between these two result sets? I was considering a Pearson correlation, but after thinking about things more I don't believe that it is the most appropriate correlation metric. My data looks similar to below:
Before After 1 2 1   2 2   2 3   3 3   4 4   2
Result: XXX?
Thanks all
