geometric mean

Also known as GM, proportional mean, geometric mean value, geometric average

the n-th root of the product of n numbers

AI overview

The geometric mean is a way of averaging a group of numbers by multiplying them together and then taking the appropriate root—for example, with two numbers you'd multiply them and take the square root. It's particularly useful when dealing with rates of change, growth over time, or comparing quantities that vary widely, since it naturally accounts for proportional differences rather than just adding them up like a regular average would.
