GEOMEAN(n1,n2,…)
- are the positive real numbers.
Description
- This function gives the Geometric Mean of an array or references.
- For example, it is used to calculate average rate of growth of human population.
- The Geometric Mean of two numbers is, the square root of their product.
- The Geometric Mean of the three numbers is, the cube root of their product.
- So the geometric mean of numbers is defined as the root of the product of the numbers.
- In , are the positive real numbers and is required. are optional.
- The arguments can be numbers,names,arrays or references that contain numbers.
- Also we can directly use logical values and text representations of numbers.
- The values are ignored, when the argument contains logical values or empty cells.
- The Geometric and Arithmetic Means are equal, when all the numbers in the given set are equal, otherwise the Geometric Mean of a data set is less than the data set's Arithmetic Mean.
- The geometric mean of a data set is given by:
- This function will give the result as error when
1.Any one of the argument is non-numeric 2.Any one 3.Any one of the references cannot be translated in to numbers.
Examples
- =GEOMEAN(3,27) = 9
- =GEOMEAN(2,4,8) = 4
- =GEOMEAN(3,5,8,10,12) = 6.786916380543178
- =GEOMEAN(-2,32) = NAN, because the value is < 0.
