Dr. Hernandez studies the causes, consequences, and treatments of schizophrenia. In her current study, she is examining whether six people diagnosed with schizophrenia improve from baseline after receiving a new drug being tested to alleviate the symptoms of the disease. She measures two different variables at pre- and post-drug ingestion, one being levels of a neurotransmitter and the other being levels of positive symptoms of the disease. The results for each of the variables are displayed in the tables below

Schizophrenia is a serious mental disorder that causes people to have an abnormal interpretation of reality. Some symptoms of this disease are:
