Using Visuals

Statistics is the study of the collection, analysis, interpretation, presentation, and organization of data.

Because data represent facts, incorporating statistics in your persuasive speech can be an effective way of adding both context and credibility to your argument.  Your audience is much more likely to believe you if you incorporate statistics.

Statistics can be difficult to understand on their own, though. As a result, consider using visual tools such as tables, graphs, and maps to make statistics more understandable for your audience. These visuals are often easier to understand than raw data.
