Show answer & explanation
Correct answer: D
Answer: Nominal → Ethnicity; Ordinal → Satisfaction level; Interval → Year of death; Ratio → Weight.
Explanation:
Nominal — Ethnicity: categories with no inherent order (e.g., different ethnic groups).
Ordinal — Satisfaction level: ordered categories where the order matters but intervals between categories are not necessarily equal (e.g., dissatisfied, neutral, satisfied).
Interval — Year of death: numeric values with equal intervals where differences are meaningful but there is no natural zero that allows meaningful ratios.
Ratio — Weight: numeric scale with a true zero (zero means absence of the quantity), so both differences and ratios are meaningful.
