Which term describes a preliminary study conducted to test the procedures of the research?

• A. Protest Study
• B. Proposal
• C. Test-Retest
• D. Pilot Study

Answer: (D)

Pilot studies are small, initial trials used to test research procedures before the full study. They let you check data collection tools, recruitment plans, consent processes, and timing, and reveal practical issues—like unclear questions or bottlenecks in data entry—so you can refine the protocol, minimize risks, and confirm resources are adequate. This rehearsal improves study quality and efficiency when moving to the larger project. The other terms don’t describe this preparatory testing: a proposal is a plan for the study, not a test run; test-retest assesses the stability of a measurement over time; and the concept of a protest study isn’t a standard research method.
