Chapter 2 Graphical methods for presenting data
CHAPTER 2. GRAPHICAL METHODS FOR PRESENTING DATA 16 2.2.1 Using Minitab With the small data sets we have seen so far, it is obviously relatively easy to create stem and leaf plots by hand. With larger data sets this would be more problematic and certainly more time consuming. Fortunately, there are computer packages that will create these plots ...
