What is validity and availability of norms?

Validity: It assesses the extent to which a test measures what it is designed to measure. It ensures that the test is relevant and accurately evaluates the construct of interest. Norms: Norms are the reference values derived from the standardization process.

How validity reliability and norms help to evaluate tests?
