Box and whiskers plots use five number summaries. The first number is: 1:Minimum 2.Quartile 1 3.Mean 4.Quartile 2 5.maximum
Quartile are simple to get. If your set of numbers is: 2,3,3,6,8,8,11 Then find the mean 2 3 3 |6| 8 8 11 Find the mean of the left side of of mean. 2 |3| 3 3 =Quartile 1 Then the right side 8 |8| 11 8 =Quartile 2 ----------------------------------------------- Your 5 number summary is 2,3,6,8,11 Plot them on the number line, but put a line above where the dot would go. take the 3 middle lines and connect to make a box. The lines on the outside of the box are the whiskers, AKA distributed data.
