Researchers have sought to examine the effect of various types of music on anxiety levels in patients who are in the early and middle stages of Alzheimer's disease. Patients were selected to participate in the study based on their stage of Alzheimer's disease. The participants in the two different stages of Alzheimer's are not related to each other and their anxiety levels are normally distributed within each group. Three forms of music were tested: heavy metal, smooth jazz and classical music. While listening to music, anxiety levels were recorded for the patients with a high score indicating a higher level of anxiety. Scores are recorded below.
