The Second Edition of An Applied Guide to Research Designs offers researchers in the social and behavioral sciences guidance for selecting the most appropriate research design to apply in their study. Using consistent terminology, the authors visually present a range of research designs used in quantitative, qualitative, and mixed methods to help readers conceptualize, construct, test, and problem solve in their investigation. The Second Edition features revamped and expanded coverage of research designs, new real-world examples and references, a new chapter on action research, and updated ancillaries.
The exploratory-sequential approach is a sequential approach and is used when the researcher is interested in following up qualitative findings with quantitative analysis. This two-phase approach is particularly useful for a researcher interested in developing a new instrument, taxonomy, or treatment protocol (Creswell & Plano Clark, 2011). The researcher uses the qualitative (exploratory) findings from the first phase to help develop the instrument or treatment and then tests this product during the second phase (quantitative). In general, when variables are unknown, [Page 202]this approach is useful to identify important variables (Phase 1) for subsequent quantitative analysis (Phase 2). It is also a useful approach for revising existing instruments and treatment protocols, as well as for developing and testing a theory. Although the ...
