Which statement identifies the four levels of measurement included in NOIR?

• A. Nominal, Ordinal, Interval, Ratio
• B. Binary, Categorical, Continuous, Discrete
• C. Primary, Secondary, Tertiary, Quaternary
• D. Abstract, Concrete, Theoretical, Applied

Answer: (A)

The measurement scales identified in NOIR are Nominal, Ordinal, Interval, and Ratio. This set is the standard way to classify data by how much information the scale conveys and what arithmetic you can perform with it. Nominal scales categorize data into named groups with no inherent order—labels like types or categories. Ordinal scales add a meaningful order, so you can say one value is higher or lower than another, but the intervals between ranks aren’t guaranteed to be equal. Interval scales introduce equal spacing between values, so differences are meaningful, yet there isn’t a true zero element to indicate the absence of the quantity. Ratio scales have both equal intervals and a true zero, which allows meaningful statements about how many times greater one value is than another. The other options mix different notions that aren’t the recognized levels in NOIR. Binary, Categorical, Continuous, and Discrete describe data types or formats rather than the hierarchical measurement levels. Primary, Secondary, Tertiary, Quaternary, and Abstract, Concrete, Theoretical, Applied aren’t used to classify measurement scales.
