a constant value 10 is subtracted from each value of a series the coefficient of variation will be?
Solution:
Variance is the mean of the squares of the deviations from the mean. It is not affected by the addition, subtraction, multiplication, and division of the given value. Therefore, if each value of the series is reduced by 10, the coefficient of variation will remain unchanged.
