A line across the box indicates the median. A box and whisker plot is a type of graphical display that can be used to summarise a set of data based on the five number summary of this data. The summary statistics used to create a box and whisker plot are the median of the data, the lower and upper quartiles (25% and 75%) and the minimum and maximum values. A box & whisker plot shows a "box" with left edge at Q 1 , right edge at Q 3 , the "middle" of the box at Q 2 (the median) and the maximum and minimum as "whiskers". Note that the plot divides the data into 4 equal parts. The left whisker represents the bottom 25 % of the data, the left half of the box represents the second 25 % , the right ... 5) Draw a box that begins at the lower quartile and ends at the upper quartile. 6) Draw whiskers from both ends of the box.
