Patton's Evaluative Criteria
Credibility of the research
- The researcher should use rigorous techniques and methods for gathering high quality data
- Data should be carefully analyzed, with attention to issues of reliability, validity and triangulation
- Credibility of the researchers (training and experience, track record, status and presentation of self)
- Analysis should be creative, yet methodical
- Sufficient detail should be reported to allow others to judge the quality of the resulting product (audit trail)
Some techniques for achieving credibility include:
- Rigor in sampling or case selection (evidence of an iterative sampling process)
- Clear delineation of the purpose and limitations of sample studied
- Care with regard to extrapolation of findings to other situations, times, settings, people, etc.
