EVALUATING RESEARCH QUESTIONS, HYPOTHESES, AND QUANTITATIVE RESEARCH DESIGNS

Essay Instructions:
The selection of a research design is guided by the study’s purpose and research questions and hypotheses, and the design then links the research questions and hypotheses to the data that will be collected. You should keep in mind, however, that the research process is interactive, not necessarily proceeding in a linear fashion from one component to the next. Rather, the writing of research questions could, for example, necessitate adjustments to the study’s purpose statement. Nevertheless, when presented together, the various components of a research study should align. As you learned last week, alignment means that a research study possesses clear and logical connections among all of its various components. In addition to considering alignment, when researchers select a research design, they must also consider the ethical implications of their choice, including, for example, what their design selection means for participant recruitment, procedures, and privacy. For this Discussion, you will evaluate quantitative research questions and hypotheses in assigned journal articles in your discipline and consider the alignment of theory, problem, purpose, research questions and hypotheses, and design. You will also identify the type of quantitative research design the authors used and explain how it was implemented. Quasi-experimental, casual comparative, correlational, pretest–posttest, or true experimental are examples of types of research designs used in quantitative research.

Evaluating Research Questions, Hypotheses, and Quantitative Research Designs Student’s Name Institutional Affiliation Evaluating Research Questions, Hypotheses, and Quantitative Research Designs Research Questions and Hypotheses This study did not state its hypothesis explicitly. Partly, the lack of a hypothesis is linked to the design choice of the study considering an emphasis on a descriptive case study approach to select and collect data for the study. Still, the purpose of the study is to examine the efficacy of a virtual learning lab (VLL) for gifted learners. From the above purpose, the study implied the following research questions: 1 What are the operational modes of VLL, and what are its benefits to gifted learners? 2 Which historical needs and progress data fuelled the development of VLL? 3 What are some of the perceived benefits as well as challenges linked to VLL in its attempt to support learners in the 1st century? Research Design and Implementation The research design for this study was qualitative and not quantitative. Specifically, the researchers employed a qu...
