    Study Notes

    Importance of Quantitative Research

    • Quantitative research significantly contributes to solving complex problems and advancing knowledge across various fields.
    • Historical examples include vaccine development for diseases like polio and Covid-19, showcasing quantitative research's role in public health.
    • Findings from quantitative studies can shape legislation by revealing the need for interventions, such as imposing community quarantines during health crises.
    • Quantitative methodologies help clarify relationships between variables, fostering better decision-making.

    Applications Across Disciplines

    • Social Science: Assesses interventions on group behavior and explores cultural conflicts and economic stability impacts.
    • Natural and Physical Sciences: Evaluates product effectiveness and seeks advancements in material science and alternative energy sources.
    • Agriculture and Fisheries: Focuses on increasing crop yield and developing disease prevention methods for crops and livestock.
    • Sports: Investigates techniques for enhancing athletic performance.
    • Business: Analyzes marketing strategies and their effectiveness on sales.
    • Arts and Design: Studies the influence of color on architectural space and the effects of music on learning.

    Types of Variables in Quantitative Research

    • Quantitative Variables: Numeric and measurable; include discrete and continuous variables.
      • Discrete Variables: Countable whole numbers, e.g., student numbers.
      • Continuous Variables: Fractional values that can be positive or negative, e.g., height and temperature.
    • Qualitative Variables: Categorical and non-numeric; include nominal, ordinal, and dichotomous classifications.
      • Nominal Variables: Define categories without intrinsic order, e.g., blood type.
      • Ordinal Variables: Rank categories with a meaningful order, e.g., cancer stages.

    Measurement Levels

    • Interval: Meaningful differences between values, with no true zero, e.g., temperature.
    • Ratio: Similar to interval but includes a true zero, e.g., height and weight.

    Research Topic Development

    • Defining a well-structured research problem is crucial for the success of a study.
    • Four basic steps to design a research project: choose a broad topic, conduct preliminary research, define the problem, and refine the question.

    Scope and Delimitation

    • Scope outlines the boundaries of the study, while delimitation specifies what is excluded or included in the research.
    • Components include:
      • Topic of the Study
      • Variables included/excluded
      • Research objectives
      • Time frame of the study
      • Respondents' characteristics
      • Data collection methods

    Limitations of the Study

    • Delimitations are constraints identified before the research begins, while limitations arise during the study’s execution.
    • Understanding the difference helps clarify the research focus and applicability of findings.

    Research Framework

    • A research framework serves as a blueprint that guides the study and shapes research questions.
    • It encompasses key concepts and assumed relationships central to the research plan.
