UGC NET Questions (Paper – 1)

Statements A, B, C and D cover key aspects of reliability and validity, and F adds the practical step of pilot testing. A is true because internal consistency (for example, Cronbach’s alpha) assesses how well items hang together, while B is correct that content validity depends on adequate coverage of the domain. C is accurate in describing test–retest reliability, and D rightly defines construct validity. F is also true since pilot testing helps detect problematic items, whereas E is false because reliability does not guarantee validity, so validity evidence is still required.

Option A:
Option A omits statement F, overlooking the important role of pilot testing in evaluating item functioning before full-scale use. Although A, B, C and D are correct, missing F makes the combination incomplete. Therefore this option cannot be the correct answer.

Option B:
Option B is correct because it brings together A, B, C, D and F, presenting a full picture of how attitude scales should be evaluated. It appropriately excludes E, which mistakenly assumes that reliability alone is sufficient. As a result, this option contains all and only the true statements.

Option C:
Option C leaves out statement A, thus ignoring the fundamental check of internal consistency for attitude scales. Even though it includes B, C and D, missing A means not all important reliability considerations are represented. Consequently, the option is incomplete.

Option D:
Option D includes E, which wrongly suggests that valid interpretation automatically follows from high reliability. By mixing a false statement with true ones, it misleads about the relationship between reliability and validity. Hence, this combination is not acceptable.
