Which factor can diminish the accuracy of evaluation results?

Subjectivity in scoring can significantly impact the accuracy of evaluation results because it introduces personal biases and interpretations that may not align with objective standards of measurement. When evaluations rely on subjective judgments, different evaluators might assess the same performance or written work differently based on their personal views, experiences, or preferences. This variability can lead to inconsistent results, making it difficult to achieve reliable assessments or to compare outcomes across individuals or groups effectively.

In contrast, clear marking criteria provide a structured framework that guides evaluators, thereby minimizing ambiguity and subjectivity. Detailed feedback and constructive criticism are designed to enhance understanding and improvement, aligning evaluations more closely with learning objectives. These elements contribute positively to the evaluation process, as they focus on clear, measurable standards and encourage objective assessment methods. Hence, while subjectivity can lead to inaccuracies, the other factors mentioned work to ensure a more reliable and effective evaluation process.
