Calculate the coefficient of range for the following set of data: 3, 6, 6, 8, 9 and 12.
60
The coefficient of range is calculated using the formula: Coefficient of range = (Max value - Min value) / (Max value + Min value) For the data set 3, 6, 6, 8, 9, and 12, Max value = 12, and Min value = 3. Thus, Coefficient of range = (12 - 3) / (12 + 3) = 9 / 15 = 0.6, or 60%. Therefore, option 4, "60," is the correct answer.
