Example 1

easy
Find the range of the data set: {3,7,2,9,5,1,8}\{3, 7, 2, 9, 5, 1, 8\}.

Solution

  1. 1
    Identify the maximum value: max⁡=9\max = 9
  2. 2
    Identify the minimum value: min⁡=1\min = 1
  3. 3
    Apply the range formula: Range=max⁡−min⁡=9−1=8\text{Range} = \max - \min = 9 - 1 = 8

Answer

Range=8\text{Range} = 8
The range measures the total spread of a data set by subtracting the smallest value from the largest value. A larger range indicates greater variability in the data.

About Range (Statistics)

The statistical range is the difference between the maximum and minimum values in a data set: range=max⁡−min⁡\text{range} = \max - \min.
