Establishing validity and reliability in qualitative research can be less precise, though participant/member checks, peer evaluation (another researcher checks the researcherâs inferences based on the instrument (Denzin & Lincoln, 2005), and multiple methods (keyword: triangulation), are convincingly used. The rejection of reliability and validity in qualitative inquiry in the 1980s has resulted in an interesting shift for "ensuring rigor" from the investigatorâs actions during the course of the research, to the reader or consumer of qualitative inquiry. It can be enhanced by detailed field notes by using recording devices and by transcribing the digital files. endstream

RESEARCH METHOD Since reliability and validity are rooted in positivist perspective then they should be redefined for their use in a naturalistic approach. Although the tests and measures used to establish the validity and reliability of quantitative research cannot be applied to qualitative research, there are ongoing debates about whether terms such as validity, reliability and generalisability are appropriate to evaluate qualitative research. However, since it cannot be quantified, the question on its correctness is critical. 51 0 obj
