"Mean" is another word for "average," and is calculated by dividing the sum of the numbers in the set by the number of terms in the set.

True, as far as it goes. But it goes only as far as arithmetic mean. There are also the geometric and harmonic means.
The geometric mean of a set of n positive numbers is the nth root of their product.
The harmonic mean of two numbers x and y is 2/(1/x + 1/y)
Both definitions can be extended to three or more components.
Although the harmonic mean may appear to be a mathematical curiosity and a rather pointless measure, consider this example:
You travel a distance of 100 km at a speed of x km per hour. You drive back at y km per hour. What is your average speed for the round trip? It is NOT the "average" of x and y = (x+y)/2 but the harmonic mean of x and y.
