Evaluating Research Questions, Hypotheses, and Quantitative Research Designs

For this Discussion, you will evaluate quantitative research questions and hypotheses in assigned journal article 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. 

Discuss a critique of the research study in which you:

• Evaluate the research questions and hypotheses using the Research Questions and Hypotheses Checklist as a guide

• 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 and Response Post with reference to the week’s Learning Resources and other scholarly evidence in APA Style.

Evaluating Research Questions

Research Questions and Hypotheses Checklist 

Use the following criteria to evaluate an author’s research questions and/or hypotheses. Look for indications of the following:

• Is the research question(s) a logical extension of the purpose of the study?

• Does the research question(s) reflect the best question to address the problem? 

• Does the research question(s) align with the design of the study? 

• Does the research question(s) align with the method identified for collecting data? If the study is qualitative, does the research question(s) do as follows? 

• Relate the central question to the qualitative approach 

• Begin with What or How (not Why) 

• Focus on a single phenomenon 

• Use exploratory verbs 

• Use non-directional language 

• Use an open-ended format 

• Specify the participants and research site 
If the study is quantitative: 

• Do the descriptive questions seek to describe responses to major variables? 

• Do the inferential questions seek to compare groups or relate variables? 

• Do the inferential questions follow from a theory? 

• Are the variables positioned consistently from independent/predictor to dependent/outcome in the inferential questions? 

• Is a null and/or alternative hypothesis provided as a predictive statement? 

• Is the hypothesis consistent with its respective research question? 

• Does the question(s) and/or hypothesis specify the participants and research site? If the study is mixed methods, do the research questions and/or hypotheses do the following? 

• Include the characteristics of a good qualitative research question (as listed above) 

• Include the characteristics of a good quantitative research and/or hypothesis (as listed above) 

• Indicate how the researcher will mix or integrate the two approaches of the study 

• Specify the participants and research site 

• Convey the overall intent of the study that calls for a mixed methods approach

Evaluating Research Questions, Hypotheses, and Quantitative Research Designs

Canfield, Kivisalu, Van Der Karr, King, and Phillips (2015), present a discussion on the validity of the use of course grading as an effective method of assessing the learning outcomes of students. The research questions used in the study are in line with the purpose of the study. The descriptive questions used in the article seek to describe the responses to the main variables through the assessment of discriminant and convergent validity.

The inferential questions seek to both compare groups and relate inter-group and intra-group variables. These inferential questions follow the multitrait-multimethod (MTMM) of assessment. The research questions used in the study also align with the chosen technique of analysis of the collected data (Babbie, 2017, pp. 426 – 438). In this case, the choice of the multitrait-multimethod aligns with the research questions.
