    Study Notes

    Unit 1: Quantitative Research

    • True Experimental Research: Aims to establish cause-effect relationships through randomized samples.

    • Quasi-Experimental Research: Similar to experimental research but lacks randomization due to ethical or practical constraints.

    • Characteristics of Quantitative Research:

      • Controllability: Conducted in a controlled environment identifying all variables.
      • Generalizability: Findings from a larger sample are useful for the entire population.
      • Objectivity: Data is measurable using structured instruments.
      • Replicability: Research can be repeated by others yielding similar outcomes.

    • Strengths and Weaknesses: Offers insights into variable relationships, influencing decisions in various fields. Innovations often stem from quantitative studies.

    • Types of Quantitative Research:

      • Descriptive
      • Comparative
      • Correlation
      • True Experimental
      • Quasi-Experimental

    Unit 1: Variables in Quantitative Research

    • Definition of Variables: A variable is an element that can take on various values.
    • Types of Variables:
      • Numerical Variable: Can be measured (includes discrete and continuous).
        • Discrete Variables: Countable (ex: number of students).
        • Continuous Variables: Measurable with fractional values (ex: height, temperature).
      • Categorical Variable: Descriptive, non-numeric categories.

    Unit 2: Designing Research

    • Steps to Develop Research Topic:

      • Choose a broad, interesting, significant, and relevant topic.
      • Conduct preliminary research.
      • Define the problem and refine the question.

    • Research Title Guidelines:

      • Offer an accurate description of the study's subject and scope.
      • Limit title length to 5-15 words, ensuring clarity and relevance.
      • State in declarative form without unnecessary phrases and abbreviations.
      • Include independent and dependent variables, locale, and respondents.

    Unit 2: Background of the Study

    • Elements of the Background:
      • Explains the context and significance of the research.
      • Includes a theoretical framework and conceptual framework.
      • Clearly states the problem, hypothesis, significance of the study, and scope limitations.

    Unit 2: Significance of the Study

    • Purpose: Justifies the study's relevance to stakeholders; identifies benefits and beneficiaries.

    Unit 3: Research Frameworks

    • Theoretical Framework: Anchors studies in existing theories that connect findings to underlying knowledge.
    • Conceptual Framework: Represents the beliefs and ideas supporting the research.

    Hypothesis Definitions

    • Hypothesis: A testable prediction expressing a potential relationship between variables.
    • Null Hypothesis (Ho): Indicates no relationship exists between independent and dependent variables.
    • Alternative Hypothesis (Ha): Proposes a possible relationship; tested when the null hypothesis is rejected.
    • Types of Hypothesis:
      • Directional Hypothesis: Specifies the nature of the relationship (increase/decrease).
      • Non-Directional Hypothesis: Does not specify the relationship type.

    Types of Research Hypothesis

    • Categories include:
      • Simple
      • Complex
      • Empirical
      • Logical
      • Statistical
      • Null
      • Alternative
