    Study Notes

    Characteristics of Quantitative Research

    • Emphasizes numerical data and statistical analysis to uncover patterns.
    • Aims to find generalizable truths through structured methodologies.
    • Primarily uses surveys and questionnaires for data collection.

    Research Design Types

    • Non-Experimental Research Design:

      • Focuses on describing associations between variables without manipulation.
      • Suitable for evaluating marketing, social behaviors, and environmental factors affecting students.

    • Experimental Research Design:

      • Investigates cause-and-effect relationships using manipulation of independent variables.
      • Requires a control group and random assignment of participants to minimize bias.

    Non-Experimental Research

    • Explores various variables without establishing causation.
    • Commonly utilized to assess social media impact, academic performance, and anxiety levels.

    Experimental Research Designs

    • Independent Variable: The factor manipulated by the researcher.
    • Dependent Variable: The outcome measured to assess the effect of the independent variable.

    Types of Experimental Research

    • Pre-Experiments: Simplest design with minimal control; single group observed post-treatment.
    • True Experiments: Rigorously designed studies to determine causal relationships with random assignment.
    • Quasi-Experiments: Resembles true experiments but lacks random assignment of participants.

    True Experimental Design Types

    • Post-test-only Control Group Design: Participants do not undergo pre-testing to prevent bias.
    • Pre-test/Post-test Control Group Design: Measures participants before and after intervention, allowing evaluation of changes.
    • Solomon Four-Group Design: Combines both pre-testing and post-testing with multiple groups to assess treatment efficacy.

    Solomon Four-Group Important Notes

    • Random assignment of participants ensures unbiased results.
    • Pre-test measurements are only given to certain groups, while all groups receive post-test measurements.

    Limitations of Research Design

    • Non-experimental designs may not capture causation; they primarily reveal correlations.
    • Experimental designs require careful control of variables to yield valid results.
