What is the Multiple Bar Graph Activity?

The Multiple Bar Graph applets allow the user to graphically display several data frequencies using multiple bar graph. This particular applet allows the user to enter his/her own data as well as manipulate the y-axis values. The ability to manipulate the y-axis values allows the creation of potentially misleading graphs.

Bar graphs similarly to histograms are graphical data representations based on frequency. Histograms are a type of bar graph. The feature which distinguishes a histogram from a bar graph is that the each bar on a histogram represents a range of data, where each bar on a bar graph represents a specific category. For example:



In this bar graph each bar represents a specific part of this student's day, while the y-axis shows the number of hours.
