Characteristics of Quantitative Method

A
  1. Structured Research Instruments: Quantitative research typically uses tools like surveys,
    questionnaires, or equipment that provide measurable and repeatable data. These instruments
    are designed to ensure consistency across all participants and settings.
  2. Numerical Data: The cornerstone of quantitative research is its reliance on numerical data. This
    data can be easily quantified and subjected to statistical analysis, allowing for precise and
    objective conclusions.
  3. Statistical Analysis: Quantitative methods employ statistical techniques to analyze data. This
    includes descriptive statistics to summarize the data and inferential statistics to make predictions
    or test hypotheses.
  4. Objective Methodology: This approach is designed to maintain objectivity and minimize
    researcher bias. The research process is often detached from the researcher, allowing for
    findings independent of personal feelings or beliefs.
  5. Control and Manipulation of Variables: In experimental designs, quantitative research involves
    manipulating variables to observe effects on dependent variables. This helps establish causal
    relationships.
  6. Large Sample Sizes: Quantitative studies often require large sample sizes to ensure the reliability
    of results and the ability to generalize findings to a broader population.
  7. Replicability: Due to its structured nature, quantitative research can be replicated in other
    settings, allowing for the validation of results through repeated studies.
  8. Generalizability: One aim of quantitative research is to produce findings that can be generalized
    to larger populations. This is achieved through the selection of representative samples and the
    application of standardized procedures.
