E.g. if the exams marks for a class are 80+/- 10, and one person gets a say, 34 (unfortunately), a long line till 34 would misrepresent the data. Or to quote some website on the net: "Sometimes there is ONE piece of data that falls well outside the range of the other values. This single piece of data is called an outlier. If the outlier is included in the whisker, readers may think that there are grades dispersed throughout the whole range from the first quartile to the outlier.
