The approaches and methods used in qualitative and quantitative research represent various research strategies and have diverse theoretical, epistemological, and ontological concerns. Every strategy will depend on how the researchers gather and analyze their data. It is important to use caution when doing research on problem-solving lessons in secondary scientific education to prevent bias in the collection and interpretation of data. Despite the fact that both methods are employed by academics, the quantitative technique is more popular because of its strengths and qualities. To measure actions, views, attitudes, and other characteristics and draw generalizations from a larger population, quantitative research is utilized. In order to express facts and identify trends in study, quantitative research uses quantifiable data. When conducting this kind of research, results are derived using statistical and mathematical tools. This review article focuses on the basic terminologies of quantitative research, its applications in various sectors and reasons why quantitative research approaches surpass qualitative research methods.
