Qualitative data is unsurpassable for richness of detail, explanatory power, and intuitive 'undeniability' -- but can the data be described as scientific? Qualitative researchers are badly in need of systematic methods for drawing conclusions; for testing them; and for communicating them. Miles and Huberman have designed a practical sourcebook in which strong emphasis is placed on innovative types of data display, including charts, graphs, matrices and networks. Forty nine specific methods of data display and analysis are described, explained, and illustrated, with helpful suggestions for the user.
