Clinicians at a nursing home facility want to see if giving residents a plant to tend to will help lower depression. To test this idea, the residents are randomly assigned to one of two groups: Those assigned to Group 1 will serve as the control group and will not be given a plant. Members of Group 2 will be given a small bamboo plant along with a card detailing care instructions. After 90 days, all participants will complete the Acme Depression Scale, which renders a score between 1 and 100 (1 = Low depression . . . 100 = High depression).
