This is a study guide that I recently gave my students to help them study for their unit test on graphs and probability. This study guide gives the definitions of: bar graph, pictograph, line plot, survey, data, analyze, key, and probability. Then it has sample problems dealing with the 3 graphs (line plot, picto, and bar) and a few dealing with probability (certain, likely, unlikely, as likely as/equally likely, and impossible).
I have left the study guide in the publisher format in case you would like to edit the information to be more appropriate to your specific content.
(Be warned: the zig zag border may not transfer over to you if you do now have the specific file.)
