Authors John W. Creswell and Vicki L. Plano Clark walk readers through the entire research process, from formulating questions to designing, collecting data, and interpreting results. They include updated examples from published mixed methods studies drawn from the social, behavioral, health, and education disciplines. New to the third edition is a focus on three core mixed methods designs, plus their application in a new chapter to four additional methodological approaches: intervention trials, case studies, participatory-social justice designs, and program evaluations. Also included is expanded discussion throughout on the integration of quantitative and qualitative data and results, more attention to the use of theory in mixed methods research, discussion of current advances with mixed methods research, and suggested techniques and strategies that might make a mixed methods study more effective.
