Review Questions
How do statistics enhance the persuasiveness of a speech?
Statistics enhance persuasiveness by providing concrete evidence that supports claims made during a speech.

Additionally, well-presented statistics can engage listeners and make complex topics more relatable by grounding them in tangible figures that illustrate key points.
