ABSTRACT
These two approaches usually serve different ends and use different methods: the intensive study of a few cases will tend to dig deeper, but may lose something in generality; it will probably use less formal interviewing techniques than the other, and in the analysis of results will give more prominence to non-quantified material. This is an important difference, but the methodology used for such 'field studies' or 'field experiments' is in many respects so similar to that of the social survey proper that we shall refer to them from time to time.
