Validity and reliability in qualitative research.

Validity and reliability are key aspects of all research. Meticulous attention to these two aspects can make the difference between good research and poor research and can help to assure that fellow scientists accept findings as credible and trustworthy. This is particularly vital in qualitative work, where the researcher’s subjectivity can so readily cloud the interpretation of the data, and where research findings are often questioned or viewed with scepticism by the scientific community.
