Variable

A factor that can be changed or measured in a scientific study, usually described numerically.

Independent variable

The factor that is intentionally changed or manipulated in an experiment. It influences the dependent variable.

Dependent variable

The factor that is being measured or observed in an experiment. It is influenced by the independent variable.

Quantitative research

A research approach that uses numerical data and statistical analysis to study relationships and test hypotheses.

Study Notes

Quantitative Research

  • Focuses on numerical data to describe phenomena and infer relationships
  • Employs variables (factors) to understand relationships
  • Variables are traits numerically describing objects, phenomena, or groups
  • Common in scientific inquiry for testing hypotheses
  • Two main types of variables:
    • Independent variable: manipulated factor
    • Dependent variable: measured factor affected by the independent variable
    • Variables are also called factors, representing relationships between different factors

Characteristics of Quantitative Research

  • Controllability: Researchers aim to control all variables impacting a relationship or phenomenon.
  • Generalizability: Results are representative of a larger population using larger sample sizes.
  • Objectivity: Data are measurable using structured instruments.
  • Replicability: Other researchers can reproduce the study and obtain similar outcomes.

Strengths of Quantitative Research

  • Statistical analyses aid data interpretation
  • Can undertake large-scale research to represent populations
  • Data presentation in graphs and tables simplifies understanding

Weaknesses of Quantitative Research

  • Large sample sizes require significant time and resources
  • Statistical analysis often demands expert knowledge
  • Oversimplification of observations to numerical values

Types of Quantitative Research

  • Experimental Research: Investigates cause-and-effect relationships.

    • Uses both experimental and control groups, with random assignment of participants.
    • Independent variable manipulated to observe dependent variable changes.
    • Intervention (treatment) in the experimental group

  • Components of Experimental Research:

    • Respondents (Groups): Experimental group receives treatment (intervention) and control group does not.
    • Variables: Independent variable is the treatment, dependent is the outcome.
    • Strategies of Experimental Procedure:
      • Intervention stage: variables interaction occurs
      • Pretest: before intervention
      • Posttest: after intervention
    • Instrumentation and Materials: Tools to measure observations
    • Research Designs:
      • Pre-experimental: single experimental group
      • True experiment: random assignment in experimental and controlled group
      • Quasi-experiment: groups not randomly assigned. Random sampling not possible due to inherent or ethical limitations.
      • Single-subject design: research participant only.

  • Data Analysis and Interpretation:

    • Descriptive or inferential methods (appropriate statistical tests).
    • Aim is to establish cause-and-effect, not correlation.
    • Types of research:
      • Descriptive Research: Describes variables or phenomena in nature.
      • Correlational Research: Investigates relationships between two variables.
      • Quasi-experimental Research: Similar to experiments, but cannot control all variables. Random sampling not possible due to inherent or ethical reasons.
