Victoria is conducting an experiment to determine the impact of pet visitation on life satisfaction in an assisted living center. She first measures life satisfaction in all residents using a survey. Then, Victoria randomly assigns residents to the experimental and control groups and then provides pet visitation (three times per week for 30 minutes) for the experimental group. After six weeks, the life satisfaction survey is administered again and comparisons between the control group and experimental group are assessed. In this experiment, what is the independent variable?
◦ Scores on the life satisfaction scale
◦ Receiving pet visitations or not
◦ Amount of time the pet visitations last
◦ Lifespan of the individual living in the assisted living center
