Question

Quizplus · Accepted Answer

When a data set is skewed due to outliers, the mean tends to be pulled in the direction of the outliers, making it an unreliable measure of central tendency. The median, on the other hand, is not affected by outliers and represents the central value of the data set. Therefore, the median is the most accurate measure of central tendency to report in this scenario. The mode and variance are not suitable alternatives in this situation as they do not provide an adequate representation of the data set as a whole.
