Question 44263
First rearrange the numbers in ascending order...so that
0.16, 0.08, 0.27, 0.20, 0.22, 0.32, 0.25, 0.18, 0.28, 0.27
becomes
0.08, 0.16, 0.18, 0.20, 0.22, 0.25, 0.27, 0.27, 0.28, 0.32
The 1st and 3rd quartiles are the middle points of the left- and right-hand halves of the data, so our 1st and 3rd Q's are 0.18 and 0.27
