2). When do you find facts and statistics are most effective in a speech? When are facts and statistics not as effective?
According to the text a speaker relies on facts and statistics when making a logical appeal. The speaker relies on the authors’ credibility to influence the degree to which the audience think the information is accurate (Coopman, Lull ). Source credibility is very important for facts and statistics. Facts and statistics can be wrongly interpreted; therefore, the speaker must be careful when using them. Facts and statistics are more useful in persuasive speeches because the audience finds these supporting materials more convincing.
