+A box plot or boxplot is a convenient way of graphically depicting groups of numerical data through their quartiles. 
+Box plots may also have lines extending vertically from the boxes (whiskers) indicating variability outside the upper
+and lower quartiles, hence the terms box-and-whisker plot and box-and-whisker diagram. 
+Outliers may be plotted as individual points.
