Answer:
Validity
Explanation:
Validity is the statistical term. It was formulated by Kelly. He told that the test will be valid when it measures what it claims to be measured.
For example, a test of personality will measure personality. A test in intelligence will measure the intelligence of a person rather than a personality. There is a distance between the external validity and internal validity. Different types of validity measure the test.
