how to find the geometric mean of multiple numbers Basically we multiply the numbers altogether and take the nth root of the multiplied numbers where n is the total number of data values For example for a given set of two numbers such as 3 and 1 the geometric mean is equal to 3 1 3 1 732
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 First we multiply them 2 18 36 Then as there are two numbers take the square root 36 6 In one line In order to find the geometric mean multiply all of the values together before taking the nth root where n equals the total number of values in the set You can also use the logarithmic functions on your calculator to solve the geometric mean if

How to Find Geometric Mean with Two Numbers Imagine you have two numbers of 5 and 20 and need to find the geometric mean Let s use the geometric mean formula with these numbers Multiply the two numbers 5 20 100 Because there are two values take the square root of 100 which equals 10 For GM formula multiply all the n numbers together and take the nth root of them The formula for evaluating geometric mean is as follows if we have n number of observations x geom begin array l sqrt n prod i 1 n x i sqrt n x 1 cdot x 2 cdot cdot cdot x n end array
The formula for calculating the geometric mean is where n is the number of numbers in the set and X1 Xn are the numbers from the first to the n th An alternative way to write the formula is X1 x X2 x Xn 1 n This formula is used in our calculator A geometric approach to explain the formula is through rectangles and squares Simply speaking if you are wondering how to find the geometric mean just multiply your values and take a square root for two numbers cube root for three numbers fourth root for four numbers etc Generally the geometric mean applies only to positive numbers

Basically we multiply the n values altogether and take out the n th root of the numbers where n is the total number of values For example for a given set of two numbers such as 8 and 1 the geometric mean is equal to 8 1 8 2 2 Thus the geometric mean is also defined as the n th root of the product of n numbers Answer Recall that the geometric mean of two numbers and with the same sign is Since both expressions 9 and 3 6 have even powers these quantities must be nonnegative Hence their geometric mean is given by 9 3 6 9 3 6 3 2 4
Solution Multiply those numbers together Then take the third root cube root because there are 3 numbers 3 2 8 4 4 2 8 4 3 4 As you might be expecting the geometric mean can get very complicated Here s a mathematical definition of the geometric mean Remember that the capital PI symbol means to multiply a series of numbers The geometric mean of two numbers say 2 and 8 is just the square root of their product that is The geometric mean of the three numbers 4 1 and 1 32 is the cube root of their product 1 8 which is 1 2 that is
