To compare the effects of pets and friends in stressful
situations, researchers found 45 people to take part in an
experiment. 15 of the people were assigned to each of the
3 groups to perform a stressful task alone (control group),
with a good friend present, or with their dog present. Each
person's mean (m) heart rate during the task was recorded. Higher
heart rates mean more stress. Use an alpha of .05.
