Can i use the same the techniques used for nominal data on the ordinal data. I cant seem to find help on hypothesis test for ordinal data. This question contains categories (customer satisfaction) and they are in order so the data must be ordinal but they havent taught us how to conduct a test on the ordinal data. btw why isnt there any info on conducting a test on ordinal data anywhere. Not even google can find anything. Is it even possible to conduct an inference on nominal data. Thank you.
