Facts & Statistics

As for me facts and statistics are important in speeches, because it helps to provide specific evidence. For an example, back to the video we watched Matthew give a speech about drinking, and the harmful affect of drinking and driving, he provided facts and statistics. In my point of view, providing those information captures the audience more. This is because it gives a definite number and percentage of what can happen. I don't know if that's quite understandable but here's an example. I'm sitting in class and someone is giving a speech about drinking and driving. Of course there's going to be death in this situation; although if the speaker were to just say "Death is involved in drinking an driving" it doesn't exactly grasp our attention. Giving statistics in this speech would capture my attention. For an example, "two out of ten people are killed during drunk driving." See the difference? It helps to give a steady ground to approximately how many people die from drinking and driving.
Facts and statistics are not as effective when it gets to much out of hand. For example you don't want to give all facts and just base your speech off of that. Putting in personal opinion and experience is mainly necessary to have an effective speech. Sometimes giving too much statistics can make an speech seem unreliable. Or at least it would show that the speaker is not familiar with their topic at all, because they are just giving out straight facts and statistics.
