Charlotte advised "So with ordinal data, better to use the median to report summary stats in this case, and the corresponding nonparametric statistical test (Mann-Whitney or Wilcoxon rank sums for independent samples t, Wilcoxon matched-ranks for matched samples t)."
But these "nonparametric" procedures are essentially just t tests done on ranked data. In other words, you are just applying a positive monotonic transformation to your data prior to analysis with a parametric procedure. Why not just report both mean and median (or mean rank)?
