For a given set of two numbers such as 3 and 1 the geometric mean is equal to 31 4 2. Compute geometric mean for the following frequency distribution. The geometric mean formula for ungrouped data for value X consisting n observation such as x₁x₂ x₃xn is represented by G M of X and is derived as G.
Let x_i i12 cdots n be n positive observations then the geometric mean of X is denoted by GM.
If x1 x2 xn are observations then GM Log GM GM Antilog For grouped data GM Antilog GM is used in studies like bacterial growth cell division etc. HM of X barX fracnfrac1x_1frac1x_2frac1x_3frac1x_nfracnsum frac1x. The harmonic mean is a way to calculate the mean or average of a set of numbers. X n n Properties of Geometric Mean The following are the properties of Geometric mean.
