Stem and Leaf Plots (1 of 2)
A stem and leaf display (also called a stem and leaf plot) is a graphical method
of displaying data. It is particularly useful when the data are not too numerous.
A stem and leaf plot is similar to a
except it portrays a little more precision. A stem
and leaf plot of the tournament players from the dataset "chess"
well as the data themselves are shown below:
The largest value, 85.3, is approximated
10 x 8 + 5.
represented in the plot as a stem of 8 and a leaf of 5. It is shown
as the 5 in the first line of the plot. Similarly, 80.3 is
approximated as 10 x 8 + 0; it has a stem of 8 and a leaf of 0. It is
shown as the "0" in the first line of the plot.
Depending on the data, each stem is displayed 1, 2, or 5 times.
When a stem is displayed only once (as on the plot shown above), the
leaves can take on the values from 0-9.
