Quizplus · Accepted Answer

The arithmetic mean is sensitive to extreme values, often called outliers, because it involves dividing the sum of all values by the total number of values. Thus, a large or small outlier can greatly affect the overall value of the mean. The median and interquartile range are less affected by outliers because they focus on the middle values in a dataset. The 1st quartile, while also focusing on a specific section of the dataset, is not as commonly used to measure sensitivity to outliers.
