Coefficient of variation (C.V.) is the relative measure
of dispersion.
C.V. = (Standard Deviation/Mean) X 100
Q. 11. The wage pattern of the workers of
a firm is given below:
| |
Firm |
| No.
of workers |
400 |
| Average
monthly income |
350 |
| Standard
Deviation |
8 |
Find the coefficient of variation.
Solution.
C.V. = (8/350) X 100 = 2.28%
1. Based on Standard Deviation
C.D. = Standard Deviation / Mean
2. Based on Mean Deviation
C.D. = Mean Deviation/Average
