Range is defined as what?

• A. Difference between highest and lowest values
• B. The sum of all values
• C. The average of all values
• D. The product of the extremes

Answer: (A)

Range measures how spread out a set of numbers is by looking at how far apart the largest and smallest values are. It’s found by subtracting the smallest value from the largest value in the data set. For example, with numbers 3, 7, and 5, the range is 7 minus 3, which equals 4. This differs from the sum (which adds all values) and the average (which finds the central value), and it isn’t the product of the extremes. The range reflects the overall spread using just the extreme values, giving a quick sense of how wide the data set is, though it can be influenced by outliers and doesn’t describe how the middle values are arranged.
