Range of Data
Range of Data:
The range of a set of data is the difference between the highest and lowest values in the set. To find the range, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.
Illustration 1: Find the range of the given data: {8, 11, 5, 9, 7, 6, 36,16}
Solution: Firstly arrange the data in ascending order as: 5, 6, 7, 8, 9, 16 and 36. Highest value = 36 and lowest value = 5. Range = Highest - Lowest = 36 - 5 = 31.
Illustration 2: Ms. Lumar listed 9 integers on the blackboard. What is the range of these integers?
14, -12, 7, 0, -5, -8, 17, -11, 19
Solution: Ordering the data from least to greatest, we get: -12, -11, -8, -5, 0, 7, 14, 17, 19
Highest - Lowest = 19 - -12 = 19 + +12 = +31. The range of these integers is +31.
