Which statement describes attribute data most accurately?

It is measured on a continuous scale.
It provides a quantitative measure of performance.
It indicates whether a result meets a requirement or not.
It is obtained through observation and judgement.

The correct answer is: It indicates whether a result meets a requirement or not.

The chosen statement accurately captures the essence of attribute data, which is typically used to classify items or results based on whether they meet specific criteria. Attribute data often comes from yes/no questions, pass/fail outcomes, or the presence/absence of certain characteristics. This type of data indicates a binary outcome—essentially whether a product or service meets the defined requirements or standards. Attribute data is not associated with continuous scales or exact measurements, which would imply quantifiable data like height, weight, or temperature. It also does not provide a quantitative measure of performance in the same way that variable data does; instead, it reflects quality in a more categorical manner. While it can be obtained through observation and judgement, the fundamental aspect of attribute data lies in its indication of conformity to requirements rather than the method of its collection. This is why the statement about meeting a requirement succinctly defines attribute data.
