    Study Notes

    Inquiry and Research Overview

    • Research is derived from the French word "researchě," meaning "the act of searching closely."
    • Leedy & Ormrod define research as the systematic process of collecting, analyzing, and interpreting information to enhance understanding of phenomena.
    • Creswell characterizes research as the systematic and objective creation of knowledge.

    Importance of Research

    • Establishes knowledge and improves practices.
    • Informs and contributes to policy-making.
    • Solves problems by correcting perceptions and testing solutions for effectiveness.

    Scientific Method Steps

    • Empirical Approach: Gathering real-world data and metrics.
    • Observation: Awareness of the environment forming ideas.
    • Questioning: Formulating questions that require scientific investigation for tangible proof.
    • Hypotheses: Educated guesses providing predictions about phenomena.
    • Experiments: Hypotheses must be testable under controlled conditions.
    • Analyses: Data analysis using statistical methods ensures reliability.
    • Conclusions: Drawing inferences based on verified data, avoiding bias.
    • Replication: Repeating studies with different participants for result validation.

    Qualitative vs. Quantitative Research

    • Qualitative Research: Describes characteristics and quality of a subject while interpreting events.

      • Strengths: Provides real experiences of individuals and allows in-depth responses.
      • Weaknesses: Rarely uses statistical procedures and can be biased due to the researcher's subjective interpretation.
    • Quantitative Research: Tests hypotheses and makes predictions through numerical measurements.

      • Utilizes statistical analysis for understanding data.
      • Involves tools such as surveys and questionnaires for data collection.

    Variables in Research

    • Independent Variables: Manipulated to observe effects on dependent variables.
    • Dependent Variables: Affected by changes in independent variables.
    • Controlled Variables: Kept constant to ensure valid results.
    • Confounding Variables: External factors that may affect the dependent variable but are not accounted for in the study.

    Types of Variables

    • Categorical Variables: Describe quality and are divided into:

      • Mutually Exclusive: Specific values without order (e.g., gender, civil status).
      • Extensive: Ordered categories (e.g., size classifications).
    • Continuous Variables: Measured along a continuum (e.g., temperature range).

    • Quantitative Variables: Provide numerical details (e.g., levels of satisfaction).

    • Qualitative Variables: Represent types of objects and align with categorical variables.

    Levels of Measurement

    • Nominal Scales: Concerned with names and categories (e.g., nationality).
    • Ordinal Scales: Rank data in sequential order (e.g., good, better, best).
    • Interval Scales: Use equal units for measurement without a true zero (e.g., temperature).
    • Ratio Scales: Highest level, includes a true zero (e.g., weight, height).

    Importance of Studying Variables

    • Enables proper interpretation of data.
    • Assists in decisions on appropriate statistical analyses.
