Question: Which of the following is a nominal variable?

Option 1: Income Level. This is often categorized into ordered levels such as low, middle, and high, which makes it at least ordinal. If the categories have a meaningful order, they are ordinal rather than purely nominal.

Option 2: Rating satisfaction from 1 to 5. This represents an ordered scale where higher numbers indicate greater satisfaction, which is ordinal (and sometimes treated as interval depending on analysis), not nominal.

Option 3: Age in years. This is a continuous numerical measure that has a true zero and equal intervals between values, classifying it as a ratio (and not nominal).

Option 4: Favorite diaper brand. This is a category label with no intrinsic order among brands; the categories are simply names of brands. This fits the definition of a nominal (categorical, unordered) variable.

In summary, options 1, 2, and 3 involve types of data that have some inherent ordering or quantitative meaning (ordinal or ratio), whereas option 4 consists of unordered category labels without an intrinsic ranking. Therefore, the nominal variable among the choices is the one that is a label without an order.
