Coefficient of variation (CV):
ASD / mean × 100% (relative variability, scale-free)
BCV = SD
CVariance
DMean
Answer & Solution
Correct answer: A. SD / mean × 100% (relative variability, scale-free)
CV = (SD/mean) × 100%. Dimensionless measure of relative variability. Useful for comparing variability across data sets with different units or means.
