About Geometric Mean

The geometric mean is a type of mean or average that indicates the central tendency of a set of numbers by using the product of their values. It's particularly useful when dealing with values that are products or rates.

Formula:

For a set of numbers x₁, x₂, ..., xₙ, the geometric mean is:

GM = ⁿ√(x₁ × x₂ × ... × xₙ)

Example:

For numbers 2, 4, 8:

GM = ³√(2 × 4 × 8) = ³√64 = 4
