Dr. Hernаndez studies the cаuses, cоnsequences, аnd treatments оf schizоphrenia. 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. Explain the primary reason Dr. Hernandez should be hesitant about making inferences based on her study. Describe the relationship between the neurotransmitter level and the number of positive symptoms displayed. Identify the dependent variables in the study. Describe one of the positive symptoms and one of the negative symptoms of schizophrenia that Dr. Hernandez may have measured. Explain why the study was not a true experiment. Based on the MRI below, explain the major difference between the brain of a person with schizophrenia and the brain of a person without schizophrenia.
