Question

G.M is a better measure than others when

ratios and percentages are given

interval of scale is given

Both a and b


Either a or b

​

Answer 1

A geometric mean is a mean or average which shows the central tendency of a set of numbers by using the product of their values. For a set of n observations, a geometric mean is the nth root of their product. The geometric mean G.M., for a set of

numbers $x_1+x_2+x_3$, , … , $x_n$ is given as

G.M. = $(x_1+x_2+x_3+x_n)x^{1/n}$

The geometric mean of two numbers, say x, and y is the square root of their product x,y,z. For three numbers, it will be the cube root of their products i.e., (x y z) 1⁄3.

Answer 2

interval of scale is given
