The arithmetic mean is sensitive to outliers. A single extreme score can pull the overall average above the threshold, masking the fact that the majority of individual scores are still below the threshold and require additional help.
Conditions: The decision rule relies solely on the class average score.; The dataset contains a significant outlier.; The threshold is set at 35.
