What is the difference between qualitative and quantitative data?

  • Quantitative data is used for interviews and recordings, while qualitative data is numeric.
  • Qualitative data is text-based, while quantitative data is numeric. (correct)
  • Quantitative data is text-based, while qualitative data is numeric.
  • Qualitative data is used for hypotheses testing, while quantitative data is used for problem investigation.

    • What is the purpose of an Institutional Review Board (IRB) in research?

  • To ensure that research participants' rights are protected and that the research is ethically acceptable. (correct)
  • To test hypotheses and answer research questions systematically.
  • To manipulate and control the independent variable in a study.
  • To collect both qualitative and quantitative data for research purposes.

    • What does an independent variable represent in a study?

  • The variable manipulated or controlled by the researcher, representing the 'cause' being investigated. (correct)
  • The variable being measured as the 'effect' in a study.
  • The variable used for problem investigation using text-based data.
  • The variable not being investigated or controlled for that might affect the dependent variable.

    Study Notes

    Research Basics

    • Qualitative vs. Quantitative Data: Qualitative data is non-numerical and focuses on words, meanings, and interpretations, while quantitative data is numerical and focuses on numbers and statistics.

    Ethics in Research

    • Institutional Review Board (IRB): A committee that reviews and approves research proposals to ensure they meet ethical standards, protecting human subjects from harm.

    Study Design

    • Independent Variable: The variable that is intentionally changed or manipulated by the researcher to observe its effect on the dependent variable.

    Research Methods

    • Mixed Methods Research: A methodology that combines qualitative and quantitative approaches to study a research problem.

    Research Purpose

    • Purpose Statement: A concise statement that clearly defines the research problem, significance, and goals, providing direction for the study.
    • Qualitative Purpose Statement: Focuses on exploring, discovering, or understanding a phenomenon, often using open-ended questions.

    Research Objectives

    • Research Objectives: Specific, measurable, achievable, relevant, and time-bound (SMART) goals that guide the research study.
    • SMART Rule: An acronym that ensures research objectives are Specific, Measurable, Achievable, Relevant, and Time-bound.

    Research Question

    • PICOT Approach: A framework for framing a research question, focusing on Patient/Population, Intervention, Comparison, Outcome, and Time.
    • Good Research Question: Helps to clarify the research problem, guides the methodology, and ensures the study's relevance and significance.
