This document provides instructions and examples for creating bar graphs from survey data. It explains that bar graphs can be used to compare data visually. Examples show how to construct a bar graph, including choosing an appropriate scale and labeling the bars, title, and axes. Students are then asked to create their own bar graph displaying survey results about favorite creatures.
