    Study Notes

    Nature of Quantitative Research

    Characteristics of Quantitative Research

    • Reliable and objective methodology for research.
    • Utilizes statistics for generalizing findings across a larger population.
    • Simplifies complex problems to a manageable number of variables.
    • Investigates relationships between variables to establish cause and effect, often in controlled environments.
    • Tests theories or hypotheses through systematic approaches.
    • Assumes representativeness of the sample relative to the population.
    • Subjectivity in methodology is less of a concern compared to other research types.
    • Focuses on the details of the subject rather than broader context.

    Disadvantages of Quantitative Research

    • Contextual factors may be overlooked, lacking consideration for the natural settings of studies.
    • Larger sample sizes can increase resource and time demands on researchers.
    • Results often rely on numerical analysis, potentially neglecting rich qualitative insights.
    • Provides limited narratives on human perceptions and experiences.
    • Rigor in experimental control may not accurately reflect real-world circumstances.
    • Fixed alternatives may not capture the true feelings or responses of participants.
    • Findings may be influenced by the researcher’s perspective, especially with unknown participants.

    Advantages of Quantitative Research

    • Enables measurement and detailed analysis for objective answers to research questions.
    • Generally yields reliable results due to large sample sizes.
    • Employs established standards for instrument selection, sampling, and statistical treatment, promoting replicability.
    • Reduces personal biases by minimizing direct interaction between researcher and subjects.
    • Streamlines processes, making quantitative research systematic and straightforward.
    • Interpretable findings through statistical analysis facilitate concise conclusion and reporting.

    Importance of Quantitative Research in Different Fields

    • Education: Measures performance levels of students and teachers; assesses method and program effectiveness.
    • Business: Enhances marketing strategies; informs company decisions regarding products and services.
    • Medical and Health Care: Provides statistics on patient recovery rates; evaluates the efficacy of treatments and vaccines.
    • Sciences: Promotes accountability and responsible operations in technological experiments.

    Classifications of Variables

    Types of Numeric Variables

    • Continuous Variables: Can take any value within a given range; examples include time, height, and weight.
    • Discrete Variables: Only assume whole values; examples include counts such as the number of cars or students.

    Categorical Variables

    • Ordinal Variables: Can be ranked; examples include academic grades and clothing sizes.
    • Nominal Variables: Cannot be logically ordered; examples include types of businesses and hair colors.
    • Dichotomous Variables: Represent two distinct categories; examples include gender (male/female).
    • Polychotomous Variables: Have multiple categories; examples include levels of education or performance ratings.

    Experimental Variables

    • Independent Variables: Manipulated variables within an experiment to assess their effect on other variables.

    The Research Title

    • Should encapsulate the paper's main idea and include major variables.
    • Must be concise while showing relationships among key variables.
    • Should specify the participants involved in the study.

    Title Elements

    • Main Task
    • Major Variables
    • Topic
    • Participants
    • Setting
    • Outcomes

    Reminders for Title Creation

    • Avoid using terms like "METHOD," "RESULT," or "INVESTIGATIONS."
    • The general problem can serve as the thesis title when reformulated into a statement.
