The coefficient of variation for a random variable is defined as σ/μ. This coefficient is an alternative to the standard deviation as a measure of dispersion; the coefficient of variation measures that dispersion in proportional terms. If Yi=a+bXi, what is the relationship between the coefficients of variation of Y and X?
