Range (of Data)
The range of a set of numerical data is the difference between the highest value and the lowest value.
Example:
Suppose the test scores in a class are:
37, 45, 55, 61, 63, 77, 80, 82, 86, 86, 88, 88, 89, 91, 93, 97
The highest score is 97, and the lowest score is 37. So the range of the data is
97 – 37 = 60.
