dealing with or based on norms; "a normative judgment"

Normative political knowledge addresses questions about what ought to be, rather than simply providing descriptions and explanations of what is. Examples of normative questions include: “Should there be limits on free speech?” or “How much and what types of health care should the state provide?”.

A normative scenario is one that describes a preferred future. (That's the futurists' use of the word; it has a different meaning when describing psychological testing, where it refers to comparing individuals.)

Normative text (which would be expected to make up the bulk of any specification or user publication) defines the functionality and use of the product under test. Normative text shall be tested. See also non-normative. Writers of documents which are to be tested are well advised to separate normative and non-normative text, so it is obvious which text describes the operation of the product (and shall be tested) and which text is intended as background information. Normative text is identical to text describing requirements.

normal; statistically, the results of testing a large body of people
