Discussion: Evaluating Research Questions, Hypotheses, and Quantitative Research Designs

With a clear purpose in place, quantitative researchershave a roadmap for crafting their research questions and hypotheses thatwill further focus the approach they will take to investigate theirtopic (i.e., their study’s research design).

The selection of a research design is guided bythe study’s purpose and research questions and hypotheses, and thedesign then links the research questions and hypotheses to the data thatwill be collected. You should keep in mind, however, that the researchprocess is interactive, not necessarily proceeding in a linear fashionfrom one component to the next. Rather, the writing of researchquestions could, for example, necessitate adjustments to the study’spurpose statement. Nevertheless, when presented together, the variouscomponents of a research study should align. As you learned last week,alignment means that a research study possesses clear and logicalconnections among all of its various components.

In addition to considering alignment, whenresearchers select a research design, they must also consider theethical implications of their choice, including, for example, what theirdesign selection means for participant recruitment, procedures, andprivacy.

For this Discussion, you will evaluatequantitative research questions and hypotheses in assigned journalarticles in your discipline and consider the alignment of theory,problem, purpose, research questions and hypotheses, and design. Youwill also identify the type of quantitative research design the authorsused and explain how it was implemented. Quasi-experimental, casualcomparative, correlational, pretest–posttest, or true experimental areexamples of types of research designs used in quantitative research.

With these thoughts in mind, refer to the Journal Articles document for your assigned articles for this Discussion. Ifyour last name starts with A through I, use Article A. If your lastname starts with J through R, use Article B. If your last name startswith S through Z, use Article C.

By Day 4

Post a critique of the research study in which you:

• Evaluate the research questions and hypotheses (The Research Questions and Hypotheses Checklist canbe used as a guide to facilitate your evaluation; it is not meant to beused in a Yes/No response format in writing your Discussion post.)
• Identify the type of quantitative research design used and explain how the researchers implemented the design
• Analyze alignment among the theory, problem, purpose, research questions and hypotheses, and design

Be sure to support your Main Issue Post andResponse Post with reference to the week’s Learning Resources and otherscholarly evidence in APA Style.
