What are the examples of scale of measurement?

The scale of measurement typically includes four levels: nominal, ordinal, interval, and ratio. Nominal scales categorize data without a specific order (e.g., gender or hair color). Ordinal scales rank data in a meaningful order but without consistent differences between ranks (e.g., satisfaction ratings). Interval scales have ordered categories with equal intervals between values but no true zero point (e.g., temperature in Celsius), while ratio scales possess all the properties of interval scales, along with a true zero point (e.g., weight or height).
