Educational research increasingly relies on both quantitative and qualitative methodologies to generate valid and meaningful knowledge. Quantitative approaches emphasize numerical data, standardized instruments, and statistical analysis, whereas qualitative approaches prioritize descriptive data, flexible designs, and in depth understanding of human experiences 4. However, researchers in education frequently encounter methodological challenges in planning, implementing, and interpreting both types of studies. This review based paper aims to (a) explain the concepts of quantitative and qualitative research, (b) identify the major challenges in each approach, and (c) suggest practical solutions for improving research quality. Drawing on standard journals and methodological texts, the paper highlights key issues such as sampling and measurement problems, statistical complexity, limited generalizability, subjectivity, time intensive procedures, and lack of standardization 9. The discussion compares challenges across paradigms and advocates mixed methods designs, better researcher training, appropriate use of software tools, and stronger attention to validity, reliability, and ethics. It concludes that an informed and reflective use of both quantitative and qualitative methods is essential to enhance the rigor and relevance of educational research.
