Grading bias is easier to demonstrate on what type of tests?

Grading bias is easier to demonstrate on subjective tests. This is because subjective tests rely on the opinions and interpretations of the evaluator rather than on standardized responses. Subjective assessments include essay questions, open-ended responses, or any evaluation where the instructor's judgment plays a significant role in determining the score.

In contrast, objective tests typically consist of multiple-choice, true/false, or fill-in-the-blank questions, where there is a clear right or wrong answer. The lack of subjective interpretation in objective tests makes it difficult for grading bias to occur, as scores are strictly based on correctness rather than personal judgment.

Performance-based and portfolio assessments, while they may also have subjective elements, are often judged against specific criteria or rubrics that can mitigate bias. The use of clearly defined expectations and performance standards helps ensure that the evaluation is fair and consistent across different students. Therefore, the type of test that showcases bias more readily is the subjective type, given its reliance on personal assessment and interpretation.
