Measures of Frequency: * Count, Percent, Frequency * Shows how often something occurs * Use this when you want to show how often a response is given. In determining what type of graph to make, it is often useful to sketch out a graph to see whether it makes sense or is expressing the idea you wish to convey. A bar graph would also be useful for displaying people’s opinions on a particular issue, where the bars might be labeled in order from “Strongly Disagree” up through “Strongly Agree.” For numerical data such as height, weight, time, or amount, different types of graphs are needed.
