| the mean of n positive numbers obtained by taking the nth root of the product of the numbers: The geometric mean of 6 and 24 is 12. |
| geometric mean n. The nth root, usually the positive nth root, of a product of n factors. |
geometric mean n.
The nth root, usually the positive nth root, of a product of n factors.
| geometric mean
The positive nth root of the product of a set of n numbers. For example, the geometric mean of 2 × 3 × 6 × 8 is the 4th root of 288, or approximately 4.12. |
geometric mean mathematics
The Nth root of the product of N numbers.
If each number in a list of numbers was replaced with their geometric mean, then multiplying them all together would still give the same result. The geometric mean thus gives an average "factor" in a context where numbers are multiplied together, e.g. compound interest.
