    Study Notes

    Causal-Comparative and Ex-post Facto Research

    • Seeks to establish causal linkages through comparisons between groups experiencing different treatments or situations.
    • Lacks random assignment, which differentiates it from experimental research.

    Experimental Study

    • A scientific method that alters one variable to observe its impact on another.
    • Utilizes control groups, random assignment, and maintained conditions to demonstrate cause-and-effect relationships.

    Quasi-Experimental Study

    • Similar to experimental studies in intent but does not use random assignment.
    • Relies on preexisting groups or situations for its analysis.

    Longitudinal Study

    • Involves repeated observation of the same variables over extended periods.
    • Useful for studying developmental patterns and long-term outcomes.

    Cross-Sectional Research

    • Examines a sample at a single point in time.
    • Provides a snapshot of a population or phenomenon, often used to determine prevalence and relationships.

    Nature of Inquiry and Research

    • Research is a systematic approach to gather and evaluate data aimed at understanding a subject.
    • Three fundamental steps: posing a question, collecting data, presenting findings.
    • The process includes six steps: identifying problems, reviewing literature, specifying purposes, collecting data, analyzing data, and reporting research.

    Characteristics of Quantitative Research

    • Objectivity and Reliability: Ensures objectivity through standardized measurements, enhancing reliability and trustworthiness of data.
    • Quantifiable Data: Involves data that can be quantified and analyzed statistically; collected through surveys, tests, or structured observations.
    • Big Sample Size: Generally requires larger sample sizes for findings to be generalized compared to qualitative research.
    • Applications in Various Fields:
      • Education: Quantifies student performance and assesses educational initiatives.
      • Business and Economics: Provides data for market analysis, forecasts, and decision-making.
      • Social Sciences: Investigates social phenomena, human behavior, and informs public policy using various methodologies.

    Types of Quantitative Research

    • Descriptive Research: Systematically collects data to provide detailed descriptions of specific phenomena or situations; uses surveys and observational methods.
    • Correlational Research: Explores relationships between variables without manipulating them; identifies patterns, but does not establish causation.
