Hello,
I got a question wrong on a test and I can’t understand why. It was a simple question to identify if performance rating was ordinal or interval. I put ordinal since I thought rating wouldn’t have a true “interval” between each number. My teacher sent me a message saying "You're confusing rating (interval) with ranking (ordinal)." I know that customer satisfaction ratings are often confused to be interval but are actually ordinal, so how is performance rating different?

Data Set:
