Question

In two factories A and B, located in the same industrial area, the average weekly wages in rupees and the Standard Deviation are as follows:

Factory	Average of wages in Rs.	S.D. of wages in Rs.
A B	34.5 28.5	6.21 4.56

Determine which factory has greater variability in individual wages?

Answer 1

Table of calculation
Factory	Mean Wage	S.D	C.V=
A	34.5	6.21
B	28.5	4.56

The coefficient of variation for factory B is less than that for factory A.

Hence, factory A has greater variability in individual wages.
