Social anthropology vs anthropology

Anthropology broadly deals with the science that studies humans in its broadest sense, ranging from evolutionary origins, physical and cultural diversity and changes to the social and political organization of societies. I usually describe anth as bridging human biology and sociology because in order to understand humanity we must not create superficial categories such as medicine, human bio, social science, rather in order to understand the human species we need to adopt a holistic and interdisciplinary approach, this is what anthropology does. Yet, most university institutions differentiate between biological anthropology (genetics, evolution, research in labs) and social anthropology (social science, social theory, research method is ethnographic fieldwork), some also offer medial anthropology. Social anthropologist usually have nothing to do with evolution, physiology, hormones, genetics etc. whereas biological anthropologists do. Social Anth studies human cultural and social diversity, literature draws on social theory and social anth have developed their own unique method: ethnography/participant observation. This means that their empirical work is based on the collection of QUALITATIVE data, rather than quantitative; anthropologists go to the field (a field site can be the village where ebola outbreaks frequently occur, north east Harlem, gehttos in London to study youth culture, populations with high numbers of teenage pregnancy, divorce rates, or heart disease rates, or something more "exotic" such as the impact of the buildings of dams in papua new guinea or the consequences of genetically engineered crops in the amazon) where they spend months or even years to try to understand the "native's point of view", to answer the WHY and HOW questions regarding human behavior, questions which cannot be fully answered by applying quantitative methods/statistics.
So, to respond to your questions, if they offer a "social anth" course, then most likely by saying "anthropology" only, they mean biological anthropology.
