Analysis and substantiation of research designs: exploring quantitative, qualitative and mixed approaches based on Creswell & Creswell (2018)

Abstract

This article focuses on the analysis and foundation of research designs, based on Creswell & Creswell's work titled "Research Design: Qualitative, Quantitative, and Mixed Methods Approaches" (2018). The quantitative, qualitative, and mixed methods approaches presented in this work are explored to provide a clear and concise understanding of each design and its applicability in research. The analysis is divided into three main sections. Firstly, the proposed quantitative designs by Creswell & Creswell, such as Survey Design and Experimental Design, are examined. Their characteristics and utility in obtaining reliable quantitative data are highlighted. Secondly, qualitative designs, such as Narrative, Phenomenology, Ethnography, Case Study, and Grounded Theory, are explored. Their natures are analyzed, emphasizing their ability to obtain in-depth qualitative data and explore phenomena from subjective perspectives. Lastly, mixed methods design which combine quantitative and qualitative elements, are presented. Sequential Exploratory Design, Sequential Explanatory Design, Concurrent Design, and Embedded Design are discussed, emphasizing their importance in gaining a more comprehensive understanding of the investigated phenomena. The methodology of Grounded Theory is chosen as the approach for this article, highlighting its ability to develop theories from collected data. The importance of basing conclusions on the data itself is emphasized, ensuring the validity and reliability of the findings.
