Which data type has no natural order?

Which data type has no natural order?

• A. Ordinal
• B. Nominal
• C. Interval
• D. Ratio

Answer: (B)

Nominal data consist of categories that are just labels with no inherent ranking. There’s no meaningful order between the categories, so you can name or count them but you can’t say one category comes before another or that there’s a consistent progression across categories. This contrasts with ordinal data, which has a defined order but unequal or unknown gaps between ranks; interval data, which are ordered with equal spacing but no true zero; and ratio data, which have both equal intervals and a true zero. Because nominal values lack any inherent ordering, it’s the data type without a natural order.
