The Research Method Used to Convince Un-Banked People to Start E-Banking: Cluster Sampling as a Methodology to Pick a Reliable Sample

This paper provides a critical review of a research study on the factors influencing e-banking adoption among digitally unbanked seniors in South Africa. The critique evaluates the study's methodological rigor, theoretical foundation, and the validity of its core arguments. While the study's research design, including its multi-stage cluster sampling and sample size calculation, is technically robust, this analysis reveals significant flaws in its intellectual foundation. The study's philosophical stance is internally contradictory, and it contains severe citation errors, most notably the conflation of Structural Equation Modeling (SEM) with Scanning Electron Microscopy (SEM). The critique concludes that the study, despite its methodological strengths, is fundamentally undermined by these errors. This commentary contributes to the academic discourse on research integrity and the responsible application of quantitative methods in social science.
