This paper argues that the current sampling methods selection amongst researchers is based on normative or opinionated reasoning that lacks particularity and focus. Researchers fail to give justifications for the choosing of the sampling method during research process. This paper asserts that it is, not the research approach that determines the sampling method, but the nature of the population of the study.
