We have so far discussed validity and reliability in quantitative research. When it comes to qualitative research, some scientists question the validity and reliability in qualitative findings. In lesson 15 (https://youtu.be/2SxeRbnHNs8), we said Positivists normally questions the trustworthiness of qualitative research. This is because the researcher is the main instrument so the prospect of other researchers producing identical data and arrive at identical conclusions are equally slim. That is why qualitative researchers have come up with terms to explain accuracy rather than using the term validity. They talk of credibility and trustworthiness.
In this lecture, we are going to discuss the 8 methods of determining credibility in qualitative research.
