Question

What is the geometric mean for the following data set: 10, 10, 10, 100, 100, 1000, 10000?

Answer 1

where, n is the number of observations and x_i denotes the observations.

Here our data observations (x_i) is given as -

10, 10, 10, 100, 100, 1000, 10000

Here number of data = n = 7

Therefore,

                                                

Therefore, required geometric mean = 100           (Answer)
