What is the difference between a nominal and ordinal variable?
Nominal scale is a naming scale, where variables are simply “named” or labeled, with no specific order. Ordinal scale has all its variables in a specific order, beyond just naming them. Interval scale offers labels, order, as well as, a specific interval between each of its variable options.
So sometimes nominal data may be numbers, but the number have no numerical meaning. “A person’s height” is ratio data. Nominal data has values that have no numerical meaning, such as a person’s gender (M, F) or possible colors of a new Chevy Cruz this year.
What is the difference between nominal and ordinal variables?
Can a quantitative variable be ordinal?

What is a ordinal scale of measurement?
An ordinal scale is a scale (of measurement) that uses labels to classify cases (measurements) into ordered classes. Note that an ordinal scale implies that the classes must be put into an order such that each case in one class is considered greater than (or less than) every case in another class.

What is an example of a nominal level of measurement?
