Copy and paste (or type) your numerical statistics data into the box above. Then press 'redraw' to see the quartiles calculated and a boxplot drawn.
Once you have 'drawn' one set of data, a new input-box will appear to enter a second set of data. Press 'redraw' to see a stacked boxplot (box and whisker graph plot) of both sets of data. Keep adding as many boxplots as you like.
