Put the numbers in ascending order.
35, 39, 40, 45, 60
--
Find Q3, the data value that has 75% of the data below it:
locator: 0.75(5) = 15/4 = 3.75
Round up to 4:
Q3 is the 4th element = 45
----
Find Q1, the data value that has 25% of the data below it:
locator: 0.25(5) = 5/4 = 1.25
Round up to 2:
Q1 is the 2nd element = 39
-----
The interquartile range = Q3-Q1 = 45-39 = 6
