HOW IS THE RANGE CALCULATED?

The range is calculated by subtracting the lowest value from the highest value of a data set.



Let us look at the following working example.

Employment details of 'The Widget Company'
Observation	Position in company	Salary ($)
1	CEO	100 000
2	Manager	60 000
3	Manager	60 000
4	Factory Worker	50 000
5	Factory Worker	50 000
6	Factory Worker	50 000
7	Factory Worker	50 000
8	Trainee	40 000
9	Trainee	40 000

To get the range of the salaries, the lowest value is subtracted from the highest value.



Therefore, the range of salaries within the company is $60,000. This illustrates that there is a lot of variability between individual salaries.
