Correct Answer:
C. Multiple choice question
Multiple choice questions (MCQs) offer the most reliable marking because they have a single, unambiguously correct answer. This objectivity minimizes subjective judgment from the marker, leading to high inter-rater reliability – meaning different markers will consistently arrive at the same score for a given response.
- Completion and short answer questions, while more objective than essays, can still involve some degree of subjective interpretation regarding the completeness or accuracy of the response.
- Essay questions are highly subjective, requiring markers to evaluate content, organization, style, and argument, which can lead to significant variability in scoring among different markers.
- Therefore, MCQs provide the most consistent and reliable marking.
