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 nondirectional 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?

Page 2 of 2 • 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 Research Questions and Hypotheses Checklist

Paper For Above instruction

The evaluation of research questions and hypotheses is a fundamental step in ensuring the rigor and coherence of a research study. An effectively formulated research question or hypothesis guides the entire research process, from designing the methodology to analyzing data and interpreting results. This paper explores the criteria used to assess research questions and hypotheses across qualitative, quantitative, and mixed methods studies, drawing on the principles outlined in Walden University’s 2016 guide.

Firstly, for all types of research, the questions or hypotheses should logically extend from the study’s purpose. The purpose articulates the overarching goal, and the research questions should serve as a precise pathway towards achieving that goal. A well-aligned question ensures coherence and focus, avoiding ambiguity or misdirection (Creswell, 2014). Moreover, the questions must reflect the most appropriate inquiry to address the identified problem. This involves understanding whether the questions are sufficiently specific, relevant, and capable of offering meaningful insights into the research problem (Yin, 2018).

In relation to study design, research questions must align with the methodological approach. For qualitative studies, questions should focus on exploring phenomena rather than testing theories. Such questions typically begin with “What” or “How”, relate to a single phenomenon, and are open-ended and nondirectional, allowing for an in-depth exploration of participants’ experiences (Merriam & Tisdell, 2016). These questions should explicitly specify the research site and participants, thus framing the scope of the qualitative inquiry.

Conversely, in quantitative research, questions are often descriptive—aimed at quantifying responses to major variables— or inferential, seeking to compare groups or examine relationships among variables. These questions should logically follow from underlying theories and hypotheses. Descriptive questions provide a snapshot of variables’ statuses, while inferential questions test hypotheses about relationships or differences (Field, 2013). Variables in inferential questions must be positioned clearly as independent/predictor or dependent/outcome variables. Quantitative hypotheses, whether null or alternative, should be predictive statements directly aligned with the research questions and specify the study’s participants and setting.

Mixed methods research integrates qualitative and quantitative strategies, requiring questions that incorporate the characteristics necessary for both approaches. Such questions often specify the qualitative focus—like exploring perceptions—and incorporate quantitative elements, such as measuring variables or testing hypotheses. They must also explain how the qualitative and quantitative components are integrated or mixed throughout the study. Importantly, mixed methods questions should clarify the overall intent—whether it aims for a comprehensive understanding, corroboration, or development of insights—and include details about participants and sites.

In summary, the quality of research questions and hypotheses significantly influences the clarity, focus, and validity of a study. Careful alignment with the purpose, design, and methodology—whether qualitative, quantitative, or mixed methods—is essential for producing meaningful and credible findings. Utilizing established criteria ensures researchers formulate questions that are logical, relevant, and methodologically sound, ultimately contributing to the advancement of knowledge across disciplines.
