Which data type is characterized by ranking?

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

Answer: (A)

Ranking is the hallmark of ordinal data: it orders items so you can say which is higher or lower, but the gaps between steps aren’t assumed to be equal. This lets you compare positions on a scale such as a Likert-style agreement or a pain rating, where one score can be ranked above another without implying equal distances between points. Nominal data categories have no inherent order, so they can be labeled but not ranked. Interval data involve equal distances between points (like temperature in Celsius) but lack a true zero, while ratio data also have equal intervals and a true zero, enabling meaningful ratios. Because ranking is the defining feature, ordinal data best fits this property.
