The document discusses two major influences on the choice of research method in sociology - positivism and interpretivism. Positivism views society like the natural sciences and uses quantitative methods to study social facts objectively from the outside. Interpretivism believes behavior is influenced by personal meanings and uses qualitative methods like participant observation to understand perspectives from within by getting involved. The two approaches differ in whether they take a macro or micro view of society and use structured or unstructured, large-scale or small-scale research techniques.
