IFMINH2H397. Specifically the ends of the whiskers in the Tukey boxplot go at the nearest observations inside the inner fences which are generally at the upper hinge 15 H-spreads and lower hinge - 15 H. The vertical lines protruding from the box extend to the minimum and the maximum values of the data set as long as these values are not outliers.

The horizontal line inside the box is the median. Also looks at classifying outliers and marking them on the plotVideo 1. Here is the boxplot after adding the whiskers in Step 4.
