The Stem and leaf plot is
called stem and leaf because each data value is split into two categories, the
stem and the leaf. The leaf is
generally the last digit and the stem is usually the other digit. Stem and leaf
plots are meant to show the spread of data rather than listing a bunch of
numbers. This stem and leaf plot shows the income data for countries in Western
Africa. The lowest income data is around 80, the mean falling in between 300
and 500, and the highest being around 900.
