Which of the following describes a nominal scale of measurement?

• A. Ordered Categories
• B. No specific order
• C. Numerical values
• D. Ranked data

Answer: (B)

The identification of a nominal scale of measurement as having "no specific order" is accurate because nominal scales are used to categorize data without any quantitative value or rank associated with the categories. In a nominal scale, each category is simply a label, such as gender, breed of dog, or a type of fruit, and does not imply any hierarchy or sequence among the categories.

Nominal measurement allows for the identification of different groups or types, but it does not lend itself to mathematical operations or comparisons between them, such as determining one category is greater than another.

Other options involve different types of scales; ordered categories suggest the presence of a rank or sequence, numerical values imply measurable quantities often found in interval or ratio scales, and ranked data indicates a level of order which is not characteristic of nominal scales. Thus, the defining feature of a nominal scale is indeed that it has no inherent order among categories.
