Explanation:
First of all we have to define range.
Range gives us the difference of two values between which the data is spread.
the formula for range is:
Range = Highest value - lowest value
By observing the diagram, we can see that
The highest value is = 8.5 inches
The lowest value is: 0.9 inches
So,
Range = 8.5 - 0.9
= 7.6 inches
So, the range is 7.6 inches ..
