A researcher hears that meditation therapy has been used to treat end-of-life anxiety in terminally ill cancer patients. She decides to contact the local hospice organization in order to run a study on the effects of meditation therapy. Five cancer patients agree to be part of the study and to take part in a bi-weekly meditation class. The researcher collects the patients' anxiety scores and compares them to the anxiety levels of eight cancer patients who have not taken the meditation class.
