The geometric mean is a mean or average that indicates the central tendency or typical value of a set of numbers. Unlike the arithmetic mean, the geometric mean calculates the nth root of the product of n values.
Geometric Mean =sqrt(a_1* a_2* ⋯ * a_n)
Consider an example where the geometric mean of 2, 4, and 8 is the cube root of the product of 2, 4, and 8. sqrt(2*4*8)=sqrt(64)=4 Additionally, calculating the geometric mean of two values can be interpreted as calculating the side length of a square with the same area as a rectangle whose dimensions are the given values. Calculating the geometric mean of 2 and 4.5, for example, is finding the side length of a square with the same area as a rectangle whose dimensions are 2 and 4.5.
The side length s of the square can be calculated by taking the square root of the area.
Therefore, the geometric mean of 2 and 4.5 is 3, which is the side length of the square.
