Is there a name for a scale which mixes ordinal and nominal?
One option is create new features. One feature that is completely nominal, and another feature that is completely ordinal.
Otherwise, the scale types are &quot;rounded down&quot;. There is no danger in treating ordinal data as nominal. However, treating truly nominal data as ordinal can cause analysis problems.
There is not much literature on mixing scale types because that could easily lead to misinterpretation of results.
