Sociology is the study of societies that find themselves in close proximity, in cities, villages, offices and wherever humans come into contact with each other. These societies may vary in ethnic and racial composition - imagine the social group in a Cocacola branch, or a bunch of fans cheering their team. How they behave in specific settings can be studied by a sociologist.
Anthropology on the other hand is the study of culture within a homogenous group speaking a specific language or dialect. This includes the material culture (clothing, utensils, musical instruments, war implements etc), Music and dance, proverbs, myths and folklore, kinship, religion, their thoughts on the causes of ilness and how to treat desease. Social groups within a culture can also be studied by a sociologist.
