Star plot

The star plot is used to display data with multiple variables. It is possible to see the distance from zero that each variable goes and determine the variable with the most effect. This star plot is used for oil technologies.

Stem and leaf plot

This stem and leaf plot organizes a list of data about infant mortality rates in Western Africa. The data is organized by stem (the first digit), and then by leaf (the corresponding digits). It is then possible to see how many samples share the same first digit, and also what the other digit are.

Boxplot

This is a simple example of a boxplot. As used in this example, it shows statistics in a graphic manner that represents the median and range. The asterisks represent outlying data.
