Here's why:
* Logos relies on logic, reason, and evidence to persuade the audience.
* Statistics and specific examples provide concrete, quantifiable data and real-world scenarios that support the thesis. They strengthen the argument's credibility by demonstrating a logical connection between the evidence and the claim.
While the writer might also use other appeals like pathos (emotional appeal) or ethos (credibility appeal), the heavy use of statistics and examples strongly suggests a focus on logos.
