What is mean?

"The mean is the mathematical average of a set of two or more numbers. The arithmetic mean and the geometric mean are two types of mean that can be calculated."

What is median?

"The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average."
