Identify Numbers: Identify the highest and lowest numbers in the data set: 7, −3, 0, −4, 0. The highest number is 7 and the lowest number is −4.
Calculate Range: Calculate the range by subtracting the lowest number from the highest number.Range = Highest number - Lowest numberRange = 7−(−4)Range = 7+4Range = 11
Check Calculation: Check the calculation for any mathematical errors.The subtraction of a negative number has been correctly converted into addition.The final calculation of 7+4 equals 11, which is correct.
