Identify Numbers: Identify the highest and lowest numbers in the data set: –1, –2, –6, 8, –4. The highest number is 8 and the lowest number is –6.
Calculate Range: Calculate the range by subtracting the lowest number from the highest number.Range = Highest number - Lowest numberRange = 8−(–6)Range = 8+6Range = 14
Verify Calculation: Verify the calculation to ensure there are no math errors. 8+6 indeed equals 14, so the calculation is correct.
