Chapter 2 Graphical methods for presenting data
Stem Leaf n=10, stem unit =10, leaf unit =1. Here, the interval width is too large, resulting in only two intervals for our data. With such few intervals it is difficult to identify any patterns in the data. We can get a better idea about what is going on if we choose a smaller interval width – say 5. Doing so gives the following stem and ...
