What is geometric mean of N number of data values?
In Mathematics, the Geometric Mean (GM) is the average value or mean which signifies the central tendency of the set of numbers by finding the product of their values. Basically, we multiply the numbers altogether and take the nth root of the multiplied numbers, where n is the total number of data values.

The geometric mean is a measure of central tendency that averages a set of products. Its formula takes the nthroot of the product of n numbers. Like the arithmetic mean, the geometric mean finds the center of a dataset. While the arithmetic mean finds the center by summing the values and dividing by the number of observations, the geometric mean fi...
The geometric mean formula is the following: Where: 1. X = the values of your variable. 2. n = the number of values in your dataset. To describe this process using words, the geometric mean formula takes the nth root of the product of n values. To find the geometric mean, multiply all your values together and then take a root of it. The root depend...
First, let’s look at the more familiar arithmetic mean. This statistic calculates a number that sums to the total value of your dataset given its samplesize. Suppose your dataset has these five values: 8, 10, 12, 14, 16. They sum to 60. The arithmetic mean of these values is 60 / 5 = 12. Therefore, five 12s sum to 60: 8 + 10 + 12 + 14 + 16 = 12 + 1...
As you can saw above, the geometric mean formula involves multiplying values. Hence, when your subject area involves multiplication, consider using the geometric mean. This need often occurs when you’re working with interest rates and growth rates because they involve multiplication. When working with interest rates, you multiply the principal by t...
- Geometric Mean Definition. The Geometric Mean (GM) is the average value or mean which signifies the central tendency of the set of numbers by taking the root of the product of their values.
- Geometric Mean Formula. The Geometric Mean (G.M) of a data set containing n observations is the n root of the product of the values. Consider, if x1,x2….xnx1,x2….xn are the observation, for which we aim to calculate the Geometric Mean.
- Difference Between Arithmetic Mean and Geometric Mean. Here is a table representing the difference between arithmetic and geometric mean. Arithmetic Mean.
- Relation Between AM, GM, and HM. Before we learn the relation between the AM, GM and HM, we need to know the formulas of all these 3 types of mean. Assume that “a” and “b” are the two number and the number of values = 2, then.
The Geometric Mean is a special type of average where we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc. Example: What is the Geometric Mean of 2 and 18 ?
In mathematics, the geometric mean is a mean or average which indicates a central tendency of a finite set of real numbers by using the product of their values (as opposed to the arithmetic mean which uses their sum).
Dec 2, 2021 · The geometric mean is an average that multiplies all values and finds a root of the number. For a dataset with n numbers, you find the n th root of their product. You can use this descriptive statistic to summarize your data. The geometric mean is an alternative to the arithmetic mean, which is often referred to simply as “the mean .”
The geometric mean is a type of average , usually used for growth rates, like population growth or interest rates. While the arithmetic mean adds items, the geometric mean multiplies items. Also, you can only get the geometric mean for positive numbers.
