Research is a scientific effort to discover, develop, and verify knowledge through specific methods. In the academic world, two main approaches are commonly used—quantitative and qualitative research. Both have distinct methodologies, techniques, and objectives, yet complement each other in providing a comprehensive understanding of phenomena.
First, data can be quantitative, expressed in measurable numerical form, or qualitative, presented as narrative descriptions and meanings derived from observed phenomena. A research variable refers to anything that becomes the focus of the researcher’s attention to be studied, measured, or examined in relation to other elements. In quantitative research, variables are classified as independent, dependent, and moderating variables. Meanwhile, in qualitative research, variables are more flexible and contextual, adapting to the dynamics of the field.
Second, the population is the entire group of research subjects possessing certain characteristics, while the sample is a subset of that population chosen to represent it. In quantitative research, sampling is done probabilistically (random sampling) to ensure generalizability of the findings. Conversely, in qualitative research, sampling is typically purposive or snowball, selected based on the relevance and richness of the information needed.
Third, in quantitative research, data collection techniques include: surveys using questionnaires, tests to measure abilities or attitudes, structured observations, and experiments designed to test relationships between variables. On the other hand, qualitative research collects data through in-depth interviews, participant observations, and document studies. The aim is not to measure, but to deeply understand meanings, behaviors, and social experiences.
Fourth, in quantitative research, data analysis is conducted statistically—such as correlation analysis to identify relationships between variables and regression analysis to determine the effect of one variable on another. In contrast, qualitative research uses an inductive analysis process, moving from field data toward conceptual or theoretical conclusions. The stages include data reduction, data presentation, and drawing conclusions. Data validity in qualitative research is ensured through triangulation, which involves comparing various data sources and collection techniques.
In summary, the methodology and techniques of quantitative and qualitative research possess different yet complementary characteristics. Quantitative research emphasizes objectivity and statistical measurement, while qualitative research highlights understanding of meaning and social context. By mastering both approaches, researchers can produce findings that are comprehensive, valid, and relevant to the fields of education and management.
