geometric mean[¦jē·ə¦me·trik ′mēn] (mathematics) The geometric mean of n given quantities is the n th root of their product. Also known as geometric average. geometric mean (mathematics)The Nth root of the product of N numbers.
If each number in a list of numbers was replaced with theirgeometric mean, then multiplying them all together would stillgive the same result. The geometric mean thus gives anaverage "factor" in a context where numbers are multipliedtogether, e.g. compound interest.
