Our Data and Graphs unit shows students how to read, interpret and construct line, bar and circle graphs. Students will also learn how to determine which graph is appropriate for displaying a given set of data. You may use the free demo lessons on this page in accordance with our Terms and Conditions.

Lesson	Access	Description
Data and Line Graphs		Students are introduced to the parts of a line graph and the purpose of each part. They are then shown how to read and interpret line graphs.
Constructing Line Graphs		Students are shown how to construct a line graph from a set of data. Step-by-step procedures are listed along with large, detailed graphs for visual reference. Available on CD-ROM or by download.
Data and Bar Graphs		Students are introduced to the parts of a bar graph and the purpose of each part. They are then shown how to read and interpret horizontal and vertical graphs. Available on CD-ROM or by download.
Constructing Bar Graphs		Students are shown how to construct a bar graph from a set of data. Step-by-step procedures are listed along with large, detailed bar graphs for visual reference. Available on CD-ROM or by download.
Data and Circle Graphs		Students are introduced to the parts of a circle graph and the purpose of each part. They are then shown how to read and interpret circle graphs. Available on CD-ROM or by download.
Constructing Circle Graphs		Students are shown how to construct a circle graph from a set of data. They are shown how to compute the angle measure for each item in the circle graph. Step-by-step procedures are listed along with large, detailed graphs for visual reference. Available on CD-ROM or by download.
Comparing Graphs		Students are presented with the purpose of each type of graph learned. They are then shown how to determine which graph is appropriate for visually displaying a given set of data. Available on CD-ROM or by download.
