For example, a test designed to measure intelligence must be validated to ensure it truly captures the underlying construct of intelligence, rather than other related or unrelated abilities.
There are several methods to establish construct validity. One common approach is convergent validity, which involves
Another aspect of construct validity is known-groups validity, where a measure is used to distinguish between
