Testing the clarity of a tool or instrument for collecting information is known as (A) Pilot-test (B) Pre-test (C) Post-test (D) Summative-test Correct Ans: (A) Explanation: A pilot-test is a preliminary study conducted to evaluate the clarity and effectiveness of research tools. Researchers use it to identify errors, improve questions, and refine data collection methods before conducting the main study. For instance, before launching a large-scale survey, researchers may test a small sample to see if respondents understand the questions. If they find ambiguity, they can revise and simplify the wording. Moreover, pilot testing helps detect technical issues, response bias, or data inconsistencies. It also allows researchers to adjust procedures, estimate response time, and improve reliability. Additionally, this process saves time and resources. By addressing problems early, researchers avoid errors that could compromise results in the full study. In conclusion, a pilot-test ensures that research instruments are clear, effective, and suitable for gathering accurate information.
