Introduction to Quantitative Research

In this video lesson, the focus is on the definition and characteristics of quantitative research. Key points are highlighted below:

Definition of Quantitative Research

  • Objective Methodical Investigation: Utilizes computational procedures for an objective, methodical, and experiential investigation into recognizable phenomena.
  • Numerical Analysis: Involves the numerical analysis of data with an expectation that results can be generalized to a larger population.
  • Hypothesis Testing: Employs statistical techniques for hypothesis testing, such as analyzing relationships between variables using scatter diagrams and correlation types.

Characteristics of Quantitative Research

  1. Objectivity:

    • Focuses on precision and accuracy, avoiding intuition and guesses.
    • Prioritizes proof over discovery (e.g., COVID-19 vaccine research).
  2. Clearly Defined Research Questions:

    • Familiarity with the topic is crucial.
    • Questions must be precise and clear, defining respondents, interventions, comparison variables, and outcomes.
  3. Structured Research Instruments:

    • Instruments like questionnaires and checklists must be well-organized and planned.
    • Collects measurable characteristics (age, gender, socioeconomic status, etc.) of the population.
  4. Numerical Data Presentation:

    • Data is organized and presented as numbers and statistics, often using tables, charts, graphs, and figures.
  5. Large Sample Size:

    • Larger sample sizes yield more reliable data analysis, minimizing bias.
    • At least 20% of the population should be used as respondents.
  6. Replication (Not Duplication):

    • Studies can be repeated to verify results in different settings, ensuring validity and eliminating false conclusions.
  7. Predictive Capability:

    • Data can predict future outcomes using complex mathematical calculations and computer aids.
    • Forecasting models rely on past data patterns to predict future scenarios.
  8. Verification and Development of Concepts:

    • Research can validate existing facts or develop new ideas.

Conclusion

  • Quantitative research provides a robust framework for objective analysis and data-driven conclusions.
  • It is essential for validating existing knowledge and forecasting future outcomes.
  • The structured nature and reliance on large sample sizes make it a reliable form of research.
