Data
(See page 197)
This chapter is about ways of organizing data, or numerical information: 
A graph is a diagram that shows relationships among numbers.

A table is an organized chart or list of numbers.
 Statistics is a name for organizing and interpreting data.
 Probability is a number that expresses the likelihood that a specific event will happen.

   Graphs and Tables
(See pages 197–211)

A circle graph represents one whole amount, such as 100%. Each pieshaped piece of a circle graph represents a part of the whole.

A bar graph organizes information along a vertical axis that runs up and down one side and a horizontal axis that usually runs along the bottom.

A line graph, like a bar graph, has information on both a vertical axis and a horizontal axis. The changing data is shown on a continuous line rather than on a set of bars.

A table is a list of numbers displayed in columns and rows.
