Human Cleric - Shadows over Innistrad Tokens

Human subjects research is systematic, scientific investigation that can be either interventional or observational and involves human beings as research subjects, commonly known as test subjects. Human subjects research can be either medical (clinical) research or non-medical research. Systematic investigation incorporates both the collection and analysis of data in order to answer a specific question. Medical human subjects research often involves analysis of biological specimens, epidemiological and behavioral studies and medical chart review studies. On the other hand, human subjects research in the social sciences often involves surveys which consist of questions to a particular group of people. Survey methodology includes questionnaires, interviews, and focus groups.
