Range

Range is

  Range = Maximum observation – Minimum observation

Let’s take an example

Runs scored by Virat Kohli are 120, 24, 48, 64, 29, 64, 71, 3, 64, 29

Find range

  Range = Maximum Runs – Minimum Runs

      = 120 − 3

      = 117

Marks scored by Satvik in his test are 48, 91, 83, 83, 95.

Find range

  Range = Maximum marks – Minimum marks

      = 95 − 48

      = 47
