Quartiles
To find the lower and upper quartiles which you use to draw a box plot. You have to find the median in the numbers and then count how many numbers there are on each side of the median and find the middle number. The number on the left of the median is the lower Quartile, The number on the right of the median is the Upper Quartile. eg. 73526391429 First you order them. 12233456799 You then find the median which is 4 12233456799. Then you look at the left hand side and find the middle number which is 2. 12233456799. Then finally you find the Upper quartile which is 7. 12233456799.
