Pilot study trial run – UGC NET Question

A pilot study is a trial run of the planned research carried out on a smaller sample or in a limited setting. Its purpose is to identify practical problems in procedures, instruments, sampling or logistics before the full-scale study begins. Insights from the pilot help refine the design and improve the reliability and validity of the main research. Because the stem describes a small-scale preliminary study to test feasibility, pilot study is the correct term.

Option A:
A pilot study may reveal ambiguities in questionnaire items, difficulties in accessing participants or unexpected ethical concerns. By addressing these issues early, the researcher reduces the risk of major problems later. This exploratory testing of feasibility is exactly what the stem refers to, so pilot study fits best.

Option B:
A case study is an in-depth investigation of a single individual, group or institution using multiple data sources. It is not just a preliminary trial for a larger study but a complete research design in its own right. Therefore, case study does not match the specific purpose mentioned in the question.

Option C:
A field experiment manipulates variables in a natural setting to test causal relationships, usually forming the main research rather than a preliminary check. While it can be preceded by a pilot, it is not itself the small feasibility study described in the stem. Hence, field experiment is not the correct completion.

Option D:
Meta-analysis is a statistical technique that combines results from multiple empirical studies on the same topic to derive overall conclusions. It synthesises completed research rather than testing the feasibility of a new study, so it does not fit the stem.
