    Study Notes

    Nature of Quantitative Research

    • Quantitative research involves the use of numerical data to describe phenomena and infer relationships.
    • It is primarily focused on measuring and analyzing variables through statistical methods.

    Types of Quantitative Research

    • Descriptive Research: Focuses on detailing characteristics of a specific group or phenomenon.
    • Exploratory Research: Seeks to explore and understand a problem without providing conclusive evidence.
    • Correlational Research: Investigates the relationship between two or more variables to identify patterns or correlations.
    • Experimental Research: Tests hypotheses through controlled experiments to establish cause-effect relationships.

    Characteristics of Quantitative Research

    • Generalizability: Results can be applied to a larger population based on representative sampling.
    • Objectivity: Research is conducted without bias; data is observable and measurable.
    • Controllability: Researchers can manipulate variables to determine their impact on outcomes.
    • Replicability: Other researchers can replicate the study to verify results.

    Research Variables

    • Independent Variable: The variable that is manipulated or changed to observe effects.
    • Dependent Variable: The outcome measured to assess the impact of the independent variable.
    • Extraneous Variables: Factors that may interfere with the relationship between the independent and dependent variables.

    Hypothesis Testing

    • Formulating hypotheses is essential in quantitative research to define operational definitions and predictions.

    Strengths of Quantitative Research

    • Capable of large-scale studies due to statistical analysis.
    • Data can be effectively presented in graphical or tabular formats.
    • Objective and measurable results lead to scientific credibility.

    Weaknesses of Quantitative Research

    • Requires significant time and effort, especially with larger sample sizes.
    • Reducing observations to numbers can oversimplify complex phenomena.

    Research Design Types

    • True Experimental: Randomized samples to identify cause-effect relationships.
    • Quasi-Experimental: Similar to experimental research but lacks randomization.
    • Non-experimental: Includes descriptive, correlational, and comparative designs.

    Data Collection Methods

    • Surveys are widely used to gather quantitative data, which can include closed-ended questions for numerical analysis.

    Important Definitions

    • Causal-Comparative: Also known as causal-comparative research, it compares two or more groups to identify differences.
    • Mediating Variable: This intervenes between independent and dependent variables.
    • Moderator Variable: Influences the strength of the relationship between the independent and dependent variables.

    Notable Researchers

    • Creswell has defined quantitative research as a means for testing objective theories through relationships among variables.
    • Vanderstoep and Johnston emphasized correlational research as a measure of association between variables.
