What are Different Research Approaches? Comprehensive Review of Qualitative, Quantitative, and Mixed Method Research, Their Applications, Types, and Limitations

Abstract

There are different ways to examine and explain a study and its findings based on using numbers as a measure, a descriptive style, or a mixture of both. These three research approaches are quantitative, qualitative, and mixed methods that are commonly used by researchers in various research studies. However, with many options regarding the research design, it seems challenging for researchers to select the most appropriate approach based on the study and realize differences. This study provides a comprehensive review of qualitative, quantitative, and mixed-method research methods. Each method is clearly defined and specifically discussed based on applications, types, advantages, and limitations to help researchers identify select the most relevant type based on each study and navigate accordingly.
