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.

Investigators use this approach when they are interested in measuring the degree of association (i.e., relationship) between variables or to predict some outcome (criterion) based on the predictor variable(s). The only type of control that can be used for nonexperimental research and the observational approach is statistical procedures. Because statistical techniques are the only form of control to be applied to the observational approach, some researchers and authors tend to refer to the actual analysis as the research design. This is misleading and not accurate because the statistical analysis ...
