This clip demonstrates how to use tally charts to record survey data and use a bar graph to show the results. The video is animated and about three minutes in duration.

The concept of bar graphs is simplified by an authority in one-on-one live math tutoring, homework help, preparation of SAT, GRE, GMAT and state level tests like FCAT, ISAT, CAHSEE and others. (06:10)

A bar graph is a graph that compares amounts in each category to
each other using bars. This six-minute video will help and explain bar graphs if you've ever been curious or confused about how to read and interpret a bar graph. (06:07)

This short video uses M&M Candies to illustrate the concept of a bar graph. It provides an explanation of sorting the data and putting the information into a bar graph. (00:54)

In this video segment from Cyberchase, the CyberSquad discovers a bug problem in the Cybrary. They know that something needs to be done to stop the bugs before they eat everything in the Cybrary, so the CyberSquad creates a bar graph to display the n...umber of bugs they found in each room. Ms. Fileshare is concerned about the bug problem until she is shown a different bar graph that shows the number of bugs in each room to be much smaller. The CyberSquad must figure out why the two graphs look different and which one shows the correct number of bugs in each room. This segment is the first of three segments. Check out “Attention to Scaling" to see how the CyberSquad discovers the difference in the two graphs. Then watch “The Power of the Whole Picture” to see how they explain the difference in the two graphs to Ms. Fileshare. (04:49)[more]

In this "Cyberchase" video clip, the kids create their own bar graph to track the amount of bugs in the main Cybrary. They compare their bar graph to the one that Hacker created (to trick Ms. Fileshare, the librarian) and realize that the two bar gra...phs are based on different scales. (01:10)[more]

Students learn that a bar graph is a visual way to display and
compare numerical data (such as the population of different southern
states). The bars of a bar graph are drawn in relation to a horizontal
axis and a vertical axis, and a bar graph ca...n have either vertical or
horizontal bars. Students are then asked to create bar graphs using
given data, and answer questions based on given bar graphs. (01:21)[more]

This video explains how to interpret information on stacked and double bar graphs. Examples of both are shown with a narrator explaining how to read each. (05:10)
