WHAT ARE GEOMETRIC MEANS PLEASE SOMEBODY HELP

a type of mean or average, which indicates the central tendency or typical value of set numbers
If you have n numbers, the geometric mean is the nth root of the product of these numbers
e.g. for the numbers 4,6,7,9,22
the geometric mean is the
5th root of (4*6*7*9*22) = 8.024
Geometric mean is a mathematical concept that is used to calculate the average of a set of numbers or values. It is typically used when dealing with quantities that multiply or grow exponentially, such as rates of change or financial returns.
To calculate the geometric mean, you need to follow these steps:
1. Take the product of all the numbers or values in the set.
2. Take the nth root of the product, where n is the number of values in the set.
Let's illustrate this with an example:
Suppose we have a set of numbers: 2, 4, 8, and 16. To find the geometric mean of these numbers, we follow the steps:
1. Multiply all the numbers: 2 × 4 × 8 × 16 = 1024.
2. Take the fourth root of the product: ∛∛∛1024 ≈ 5.66.
So, the geometric mean of the numbers 2, 4, 8, and 16 is approximately 5.66.
The geometric mean is useful when dealing with situations such as calculating average growth rates, compound interest rates, or finding the average of ratios. It provides a more accurate representation of the underlying growth or progression than the arithmetic mean (regular average).
