UGC NET Questions (Paper – 1)

Statements A, B, C and E are correct descriptions of pilot studies and pre-testing, while D and F are false. Statement A is true because a pilot is a small-scale version of the main study. Statement B rightly notes that pre-testing reveals ambiguities, and statement C is correct as pilots assess feasibility of procedures. Statement E is also true since pilot data can inform sampling and variability estimates, whereas D is false because changes may be needed after a pilot and F is false because pilot work is useful even for experienced researchers.

Option A:
Option A combines A, B, C and E, capturing the main purposes of pilot studies and pre-testing while excluding the incorrect statements. It acknowledges trial runs, identification of problems, feasibility assessments and refinement of sampling. As it contains all and only the true statements, this is the correct answer.

Option B:
Option B omits E and therefore ignores the role of pilot data in refining sampling and variability estimates. Although the statements it includes are correct, the combination is incomplete because it leaves out one true statement from the list.

Option C:
Option C includes D along with B, C and E. Since D is false in claiming that no changes should be made after a pilot, any option that contains it becomes flawed. Consequently this combination cannot be considered correct even though it also includes some true statements.

Option D:
Option D contains F, which is false, and omits B. It thereby misrepresents the necessity of pilot studies irrespective of prior experience and also misses the pre-testing function of detecting ambiguous items. Mixing false statements with true ones makes this option invalid.
