Box and Whisker Plot
How to draw
To draw a box and whisker graph, you have to draw a scale that includes the highest and lowest numbers.
You then plot the highest number, lowest number,median, lower quartile and upper quartile.
Then join the lower quartile and upperquartile to make a box.
Join the boxes to the highest and lowest number with the 'whiskers'.
