A therapist wants to assess the effectiveness of different types of therapy animals on her patients' mood. She takes her patients (N = 10) and gets a baseline mood measure. Then she has each patient interact with either a puppy, a cat, a rabbit, or a hamster for 45 minutes (n = 2-3/condition). Immediately after, she measures her patients' mood again. She compares their moods after the interactions with their moods before the interactions, as well as between the different animal groups.  1. What is the DV?
