Question

in your puppy therapy experiment, what is the experimental unit? Some college campuses have started using "puppy therapy" to help reduce stress among students according to a USA Today article. Suppose you design an experiment to test the hypothesis that puppy therapy is an effective stress reducer for students, within the context of a 6-section introductory biology course at your school. Each section has 12 students. Students in three of the sections get to play together with a pack of therapy dogs for 15 minutes at the beginning of the section recitation (or "lab") meeting. The other three sections simply observe 15 minutes of quiet free time instead. Students rate their stress levels immediately after the 15-minute period. Then you measure the percentage of students that report being 'very stressed out" for each section, and you compare the average percentage between sections that played with puppies and those that didn't.
