Quantitative Method and Qualitative Approach in Educational Research: Concepts, Types, Stages, Advantages, and Roles

Quantitative research methods and qualitative research approaches have complementary roles in scientific research, particularly in the field of education. Quantitative methods play a crucial role in generating objective, measurable data that can be analyzed statistically, thus addressing research problems that require numerical evidence and generalization. Meanwhile, qualitative approaches emphasize an in-depth understanding of social phenomena by focusing on meaning, context, and participant perspectives through descriptive and interpretative analysis. This article aims to examine the fundamental concepts, types, stages or procedures, advantages, and roles of quantitative and qualitative research methods. This study employs a literature review approach by collecting data from various relevant scientific journals, books, and academic documents. Data collection techniques were conducted through documentation studies, while data analysis utilized systematic literature analysis, encompassing the processes of identification, evaluation, and synthesis of key findings. The results indicate that quantitative methods are characterized by structured, statistically-based, and generalization-oriented features, whereas qualitative approaches are flexible, holistic, and capable of exploring social realities in depth. Furthermore, qualitative approaches utilize techniques such as observation, interviews, documentation, and focus group discussions, with data analysis conducted through reduction, presentation, and conclusion drawing. The integration of these two approaches provides a more comprehensive understanding in addressing research problems and enhances the quality of research outcomes.
