What term describes a small-scale trial conducted at the start of an experiment to check for flaws, such as whether questions make sense?

• A. Descriptive Statistics
• B. Measures of Dispersion
• C. Central Tendency
• D. Pilot Study

Answer: (D)

A pilot study is a small-scale version of the research conducted at the start to test and refine the study’s design. It helps identify flaws like unclear questions, confusing instructions, or issues with how data will be collected, so you can fix them before the full study. Running a pilot saves time and improves the quality and reliability of the main experiment by ensuring the procedures and instruments work as intended. In contrast, descriptive statistics describe data after collection, measures of dispersion show how spread out the data are, and central tendency points to the typical value in the data; none of these are about pre-testing or refining the study itself.
