They suggest that a correct reading of the quantitative criteria would show that they are not limited to quantitative research alone and can be applied equally well to qualitative data.
They argue that the alternative criteria represent a different philosophical perspective that is subjectivist rather than realist in nature.
Since from this perspective, the purpose of qualitative research is to describe or understand the phenomena of interest from the participant's eyes, the participants are the only ones who can legitimately judge the credibility of the results.
Transferability refers to the degree to which the results of qualitative research can be generalized or transferred to other contexts or settings.
The researcher can actively search for and describe and There has been considerable debate among methodologists about the value and legitimacy of this alternative set of standards for judging qualitative research.
The traditional quantitative view of reliability is based on the assumption of replicability or repeatability.For instance, Guba and Lincoln proposed four criteria for judging the soundness of qualitative research and explicitly offered these as an alternative to more traditional quantitatively-oriented criteria.They felt that their four criteria better reflected the underlying assumptions involved in much qualitative research.The researcher can document the procedures for checking and rechecking the data throughout the study.Another researcher can take a "devil's advocate" role with respect to the results, and this process can be documented.
