16.33 Airport security, floppy-eared dogs, perceived friendliness, and choosing the right statistical test: A recent news headline asked, “Do Floppy-Eared Dogs Look Friendlier?” It then responded to its own question, also in the headline: “The T.S.A. Thinks So” (Mervosh, 2019). The Transportation Security Administration (TSA), which handles safety and security in U.S. airports, uses the keen noses of dogs to detect explosives. But the dogs work in public places, which can lead to fear among the traveling public. Are floppy-eared dogs less scary? Imagine that you wanted to conduct a study on this topic. Each participant sees either a photo of a floppy-eared dog or that same photo manipulated so that the dog has pointy ears. Participants must label the dog as friendly, neutral, or scary. What statistical test would you use?
