Which analysis focuses on why incorrect options (distractors) attract test-taker choices?

• A. Gap analysis
• B. Checklist
• C. Qualitative evaluation
• D. Distractor analysis

Answer: (D)

Distractor analysis focuses on why test-takers choose incorrect options and how those options perform across the group. It examines how often each wrong choice is selected, patterns among different candidates, and the misconceptions that lead to those choices. This helps item writers see which distractors are plausible but misleading, identify common misunderstandings, and judge whether an item distinguishes well between higher- and lower-performing test-takers. If a distractor is rarely chosen, it may be too obviously incorrect or not credible; if a distractor attracts many selections, it highlights a misconception to address in instruction or to revise in the item. This process improves item quality and overall test validity. Gap analysis looks at missing knowledge between curriculum and assessment, not at distractor functioning; a checklist ensures items meet design standards; qualitative evaluation provides descriptive feedback and may inform revisions, but it isn’t the specific mechanism for analyzing why distractors attract choices.
