Children who experience chronic pain as a result of medical procedures are the focus of a psychiatrist's study. Specifically, the psychiatrist wants to measure whether a new program helps decrease feelings of chronic pain in the short-term. He measures children's self-reports of pain levels before treatment on a standardized scale with a range of 0-10, with 10 being the most severe. He then administers the new program, and measures children's pain levels after treatment. Does the new treatment decrease self-reported levels of chronic pain?
