Question

When does the mean exceed the median?

Answer 1

So, the mean exceeds the median in positively skewed distributions and is less than the median in negatively skewed distributions.

Answer 2

The mean is affected by outliers that do not influence the mean. Therefore, when the distribution of data is skewed to the left, the mean is often less than the median. When the distribution is skewed to the right, the mean is often greater than the median.
