Answer:
Difference between behavioral science and health service administration is:
Behavioral science gathers information used by health service administration.
Explanation:
Behavioral science is an important branch of science (such as psychology, sociology, or anthropology) primarily concerned with human action and behavior in society.
Health service administration is concerned with the planning, directing, and coordinating medical and health services, and the administration of healthcare systems, such as hospitals, hospital networks, or large healthcare systems.
From the above definitions, it is clear that health service administration uses the information gathered by behavioral science in managing its tasks.
