The standard text for analyzing and presenting qualitative research data is Qualitative Data Analysis: A Methods Sourcebook by Miles, Huberman, and Saldaa. The Fourth Edition presents a number of fresh visual display methods for qualitative inquiry while upholding the analytical rigor of earlier versions. The now-classic matrix and network diagrams created by the original authors are supplemented by graphics. The annotated bibliography in the appendix has been updated to include new titles in research methodologies, and five chapters have undergone significant revisions.
