Question:

When is the mean less than the median in a set of numbers?

Mean and Median

The mean is the average value of a set of numbers. It is determined by computing the sum of all numbers in the set and dividing the sum by the number of numbers contained in the set.

The median is the middle value in a set of numbers. It is determined by listing the numbers in ascending order, and counting from both ends; the middle value is then the median. If the set contains an even amount of numbers, the median is determined by computing the average of the two middle values.
