Characteristics of a good test – UGC NET Question

Statements A and B correctly define validity and reliability. Statement D is true because objectivity reduces examiner subjectivity, and E is true because practicability concerns time, cost and feasibility. Statement C is false since a test can be valid and reliable yet still contain biased items, and F is false because validity and practicability are also important. Therefore, the correct set is A, B, D and E only, making option A the right answer.

Option A:
Option A includes A, B, D and E, which together describe essential attributes of effective classroom tests. Excluding C and F makes this set accurate. Hence A, B, D and E only is correct.

Option B:
Option B adds C, but C is false because fairness is not automatic even with validity and reliability. Therefore A, B, C and D only is not correct.

Option C:
Option C includes F (false) and omits reliability (B). Hence A, D, E and F only is not valid.

Option D:
Option D includes F (false) and omits validity (A). Therefore B, D, E and F only cannot be correct.

Option E includes C (false), so A, B, C, D and E only is invalid.

Option F includes C and F (both false) and omits A and B, so C, D, E and F only cannot be accepted.
