Ordinally-scaled data involves ranking the data in a particular order, but it is not appropriate to calculate mean or standard deviation as these statistics require at least interval-scaled data. The best choice for ordinally-scaled data would be percentiles and median, as they are descriptive statistics that are appropriate for ranking data. The range is also sometimes used with ordinally-scaled data, but it is not as informative as percentiles and median. The geometric mean should not be used with ordinal data.
