# Is rank a categorical variable or quantitative?

A product is rated 1 for poor and 10 for excellent. Does it strictly fall into either category - quantitative or categorical?

(Although it seems like it is categorical, I was wondering if treating it as quantitative might be helpful in terms of not having an excessive number of columns and perhaps increasing accuracy)

• It is ordinal. In that, it differs from categorial variables and from any for which you could say the difference between 5 and 6 is just as big as between 4 and 5, etc. – Michael Hardy Dec 23 '18 at 18:08

• It does make sense. What if you have N numeric variables with range from 0 to 1 and 1 ordinal variable that is not normalized. Then you encounter the same issue as having non normalized numerical variables. – gorjan Dec 24 '18 at 17:01
