    Study Notes

    Purpose of the Chapter

    • Establishes the primary intent of the study.
    • Introduces research questions and hypotheses to guide readers.

    Principles of Research Questions

    • Two forms: Central Questions (broad inquiries) and Associated Subquestions.
    • Limit subquestions to five to seven additions to the central question.
    • Central questions should relate to specific qualitative strategies.
    • Start qualitative questions with 'what' or 'how' to promote exploration.
    • Focus on a single phenomenon for thorough investigation.
    • Use exploratory verbs reflecting an evolving research design.
    • Employ open-ended questions, avoiding references to literature unless necessary.
    • Clearly specify participants and research locations in the central question.

    Designing Quantitative Research Questions

    • Formulate hypotheses that are testable through statistical methods.
    • Ensure clarity, specificity, and measurability in questions.
    • Establish relationships and predict outcomes through variables.
    • Consider research design and methodologies when framing questions.

    Importance of Research Questions

    • Help narrow the purpose statement of the study.
    • Guide the research process and inform readers about expectations.

    Types of Quantitative Hypotheses

    • Null Hypotheses: Predict no relationship or difference between groups.
    • Alternative Hypotheses: Predict specific outcomes based on existing literature.
    • Directional Hypotheses: Make specific predictions, e.g., one group will have higher scores.
    • Nondirectional Hypotheses: Predict differences without specifying their nature.

    Variables

    • Mediating Variables: Variables that lie between independent and dependent variables.
    • Moderating Variables: Affect the impact of the independent variable on the dependent variable.

    Models for Writing Questions

    • Descriptive-Inferential Model: Begin with descriptive questions followed by inferential questions that include independent, dependent, and moderating variables.

    Descriptive and Inferential Questions

    • Descriptive Questions: Aim to describe variables and their relationships.
    • Inferential Questions: Make inferences from a sample to a population.

    Mixed Methods Research Questions and Hypotheses

    • Focus on integrating qualitative and quantitative data to answer essential research questions.
