A study measure the health-related quality of life (HRQOL) of 126 persons with a disability or illness. The researchers compared the HRQOL of 50 persons who currently lived wiht a service dog with 76 persons who were on a waiting list to receive one. The researchers concluded that those who lived with a service dog had better HRQOL than those who did not. Is this an observational study or an experiment? Is it a sample survey? If is is an experiment, what is the intervention?
