Question

The following are scores made on a math test: 80, 90, 90, 85, 60, 70, 75, 85, 90, 60, 80. The range of these scores is

  1. 30
  2. 70
  3. 90
  4. 75

hintHint:

The range in statistics for a given data set is the difference between the highest and lowest values.

The correct answer is: 90


    Step 1 of 1:
    Given a set of numbers: 80, 90, 90, 85, 60, 70, 75, 85, 90, 60, 80
    Observe that, the lowest number = 60 and the highest number = 90
    So, range = 90 - 60 = 30
    Final Answer:
    The range of these scores is-- b. 30
