Geometric mean explained
WebJul 21, 2024 · For example, the geometric mean calculation can be easily understood with simple numbers, such as 2 and 8. If you multiply 2 and 8, then take the square root (the ½ power since there are only 2 ... WebThe geometric mean can be found by multiplying all the numbers in the given data set and take the n th root for the obtained result. For example, the given data sets are: 10, 15 and 20. Here, the number of data points = 3. Arithmetic mean or mean = (10+15+20)/3. Mean = 45/3 =15. For example, for data set, 4, 10, 16, 24.

Using the above dataset, the product is the multiplication of all five values: 8 X … WebWe would just sum the numbers (1 + 5 + 10 + 13 + 30) and then divide by 5, giving us an arithmetic mean of 11.80. To calculate the geometric mean, we take their product instead: 1 x 5 x 10 x 13 x 30 = 19,500 and then calculate the 5-th root of 19,500 = 7.21. In this case finding the geometric mean is equivalent to raising 19,500 to the 1/5-th ...

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). The geometric mean is defined as the nth root of the product of n numbers, i.e., for a set of numbers a1, a2, ..., an, the geometric mean is defined as or, equivalently, as the arithmetic mean in logscale:
