To compare variation in two data sets, we calculate a value called the coefficient of variation (CV). The coefficient of variation is the ratio of the standard deviation to the mean. The equation for the coefficient of variation is: Coefficient of Variation = Standard Deviation Mean 4.50 CV Stock A = = 0.175 25.70 4.50 CV Stock B = = 0.045 100.00 Let's use the coefficient of variation to compare a few data sets. Which of the following data sets has the highest relative variation? O Mean=7.00; Standard Deviation=1.64 O Mean=82.76; Standard Deviation=189.53 O Mean=150.82; Standard Deviation=201.15 Mean=172.00; Standard Deviation=25.54
