Statistical Range: Learn

The statistical range is the difference between the lowest and highest valued numbers in a set of numbers.

It is a common measure of central tendency, along with median and mean.

To find the range of a group of numbers:

  • Arrange the numbers in order by size.
  • Subtract the smallest number from the largest number.

Example: Find the range of the numbers 3, 6, 2, 6, 9, 4

  • The numbers in order are 2, 3, 4, 6, 6, 9
  • The highest number is 9
  • The lowest number is 2
  • The range is 9-2 = 7
