What Is Research Design?•Many definitions of research design•Research design is the blueprint for fulfilling research objectives and answering questions. Its essentials include: –an activity and time-based plan, –a plan based on the research questions, –a guidefor selecting sources and types of information, –a frameworkfor specifying the relationships among the study’s variables, and –a procedural outline for every research activity.BlueprintPlanGuideFramework
Research Design Descriptors•The degree to which the research question has been crystallized–Exploratory study–Formal study•The method of data collection–Monitoring–Communication Study•The power of the researcher to produce effectsin the variables under study–Experimental–Ex post facto•The purposeof the study–Reporting–Descriptive–Causal-Explanatory–Causal-Predictive•The timedimension–Cross-sectional–Longitudinal•The topical scope — breadth and depth — of the study–Case–Statistical study•The research environment–Field setting–Laboratory research–Simulation•The participants’ perceptional awareness of the research activity–Actual routine–Modified routine
6-4Research DesignResearch Design is the detail elaboration (e.g. plan/structure) of the process or the methodology to investigate the research question/hypothesis
6-5Research DesignThere can be multiple ways to reach to the answer. But the appropriate way depends on the purpose of the research and the nature of the investigative question/hypothesisDesign the research accordinglyExploratory, Causal?Observation, Survey, Experimentation?Qualitative or Quantitative Approaches?Primary or Secondary Data?Generalization or Case Study?
