Drawing from authors John Brewer and Albert Hunter's original work published in 1989, when single method research was the standard, this new text offers an explanation of how a planned synthesis of various research techniques such as fieldwork, surveys, experiments, and nonreactive studies can be purposely used to improve social science knowledge. Foundations of Multimethod Research: Synthesizing Styles explores the many aspects of the multimethod research approach, including the formulation of research problems, data collection, sampling and generalization, measurement, reliability and validity, hyposthesis testing and causal analysis, and writing and publicizing results.
