Types of validity in measurement – UGC NET Question

Statements A, B, C, D and F correctly portray validity, whereas E is false. Statement A is true because content validity concerns coverage of the relevant domain. Statement B is correct about measuring theoretical constructs, and statement C rightly deals with test-criterion relationships. Statement D correctly explains face validity as apparent appropriateness, and statement F is true since modern views treat validity as a single construct supported by multiple forms of evidence, while E is false because no test is entirely free from error even if it has good validity.

Option A:
Option A includes A, B and C but omits D and F, leaving out important aspects of validity. Face validity and the unitary concept of validity are significant in understanding how tests are judged. Consequently this option is incomplete and cannot be accepted.

Option B:
Option B adds D and F but omits B, missing the crucial idea of construct validity. Without acknowledging how constructs are measured, the description of validity remains partial. As such, this option does not list all the true statements from the set.

Option C:
Option C correctly groups A, B, C, D and F and excludes only E, which is clearly false. It presents the main recognised forms and integrative nature of validity. Because it incorporates all and only the true statements, this combination is the correct answer.

Option D:
Option D includes E, which wrongly claims that validity removes all error, and leaves out A. Including a false statement and omitting a true one makes this combination logically inconsistent.
