In plain English: basically, they’re labels (and nominal comes from “name” to help you remember). You have brown hair (or brown eyes). You are American.
Detailed explanation-2: -Ordinal data is data that can be ranked or ordered. Examples include data taken from a poll or survey. Nominal data is data that can be made to fit various categories. Examples include whether an animal is a mammal, fish, reptile, amphibian, or bird.
