Research Scenario #2 (Q7-12: 24 pts content / 10 pts format): A health psychologist wanted to examine whether walking could lower anxiety in college students. He randomly assigned participants to one of three groups - two groups were assigned to walk for 30 minutes per day, three days a week. Half were told to walk outside on the local trails ("Nature" group), the other half were told to walk on a treadmill at the local gym (gym membership was provided - "Gym" group). The third group was the control group - they were told to not begin any new exercise regimens while enrolled in the study ("Control"). Results are in the table below - higher numbers indicate greater levels of anxiety, with 3.0 indicating "average". Data are shown in the table below.
