Step 1: Identify the maximum and minimum values in the data set. The given data set is: 15, 20, 18, 12, 20, 28, 25. Maximum value (L) = 28 Minimum value (S) = 12 Step 2: Calculate the Range. The formula for Range is: Range = L - S Substitute the values: Range = 28 - 12 Range = 16 Step 3: Calculate the Coefficient of Range. The formula for Coefficient of Range is: Coefficient of Range = (L - S)/(L + S) Substitute the values: Coefficient of Range = (28 - 12)/(28 + 12) Coefficient of Range = (16)/(40) Simplify the fraction: Coefficient of Range = (16 ÷ 8)/(40 ÷ 8) Coefficient of Range = (2)/(5) Convert to a decimal: Coefficient of Range = 0.4 The range is 16 and the coefficient of range is 0.4.
