Answer 2

Given :

X 2 4 6 8 10 12

f 5 7 15 4 2 1

To find:  g.m. for the following frequency distribution

Solution:

g.m. = geometric mean

X             f               $X^f$

2             5              2⁵

4             7              4⁷

6             15            6¹⁵

8             4              8⁴

10            2             10²

12            1              12¹

            34

GM = $\sqrt[\sum f]{\prod X^f}$

GM = $\sqrt[34]{2^5\cdot 4^7\cdot 6^{15}\cdot 8^4\cdot 10^2\cdot 12^1}$

GM = 5.109

g.m. for the  given frequency distribution 5.109
