How do you create a box plot from a set of numbers

To create a box plot, you have to do as follows:

1) Order the numbers from least to greatest; make sure that if there is more than one of any number, you include ALL parts of the data

2) Find the median of the data set. You can do this by crossing off one number from each end until you get to the middle. If there are two numbers in the middle (this  will happen if you have an even amount of numbers), simply add them together and divide the sum by 2.

3) Mark the median using a line right above the number.

4) Find the median of the lower half of the numbers (that is, all the numbers that are less than your median) and make a mark there as well. This mark is referred to as the lower quartile.

5) Find the median of the upper half of the data set as well and make a mark for the upper quartile.

6) Make a dot at the greatest and least values of the data set and draw two  lines leading to the box you've made.
