The study of specific human populations for unusually high levels of a disease is an example of an ecological study, which examines the relationships between people and their environment. This type of study can help identify risk factors and potential causes of disease within a specific geographic area or population. A case-control study typically compares individuals with a disease to a control group without the disease, while a cross-sectional survey assesses the prevalence of a disease or health condition at a single point in time. A correlational experiment examines the relationship between two or more variables but does not manipulate or control for other factors that could affect this relationship.
