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. 52 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. Q1.4. In your puppy therapy experiment, what is the experimental unit? A single student A section in the course The entire course Check Answer Q1.5. In your puppy therapy experiment, how many replicates are in the experimental group? 3 Chock Answor 707 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.

Conducting the experiment multiple times during the semester, and not just a single week. Assigning sections to be in either the experimental or control group based on how easygoing the TA is for each section. Increasing replication by having 5 sections in the experimental group and one section in the control group.
