    first put the numbers in order 4,5,6,6,7,8,9,9, 10,10,12,12,14,15 first find quartile 2 (Q2).....it is the median (middle number) if there is an odd number of numbers, then the middle number is easy to find...but if there is an even number, like this one, there will be 2 middle numbers....take the 2 middle numbers and divide by 2.....so Q2 = (9 + 9)/2 = 18/2 = 9 for quartile 1 (Q1)....take all the numbers before Q2 and find the median.. 4,5,6,6,7,8,9.....and take the median (middle number) of that set of numbers. so Q1 = 6 for quartile 3 (Q3)...take all the numbers after Q2 and find the median... 9,10,10,12,12,14,15 so Q3 = 12 so the difference between Q3 and Q1 = 6
