    Study Notes

    Types of Quantitative Research

    • Four primary types: Survey/Descriptive, Correlational, Causal Comparative/Quasi-Experimental, and Experimental Research.

    Descriptive Research

    • Focuses on detailing the characteristics and components of a population or phenomenon.
    • Aims to find general attributes of existing situations and determine their frequency.

    Survey Research

    • Used to gather data from groups through sampling from a larger population.
    • Provides numeric descriptions of trends and opinions by studying a sample.
    • Collecting data from hard-to-reach populations (e.g., illegal immigrants, sex workers) presents unique challenges.
    • Self-reported information can lead to inaccuracies in questionnaires.

    Characteristics of Quantitative Research

    • Employs standardized methods to enable replication and comparability.
    • Tends to have inflexible research designs once initiated.

    Strengths of Quantitative Research

    • Minimizes researcher bias and enhances reliability through objective measurements.
    • Utilizes statistics for generalization of findings from samples to populations.
    • Allows for identification of relationships among variables and determination of cause-effect relationships in controlled settings.

    Weaknesses of Quantitative Research

    • Often lacks detail compared to qualitative methods, potentially oversimplifying complex issues.
    • Relies on the assumption that samples represent the population adequately.

    Role in Different Fields

    • In business: Assists in product design, target market analysis, and distribution strategies.
    • In STEM: Aids in investigating health trends, intervention outcomes, and cost analyses in healthcare.
    • In humanities and social sciences: Addresses social problems felt by communities and individuals.

    Variables in Research

    • Defined as measurable factors that can change based on certain conditions.
    • Include various characteristics like age, gender, or performance metrics.

    Types of Variables

    • Discrete (Nominal or Ordinal) and Continuous.
    • Discrete variables have limited distinct values, whereas continuous can take on an infinite number of values.

    Research Reflection

    • Encourages students to identify societal problems and propose research topics.
    • Highlights the importance of understanding objectives behind conducting research.
