Credibility, Validity and

By the end of this session you will be able to
describe the terms:

• Is the research believable?
• Are the researcher's conclusions supported by
the research findings?
What Makes Research Credible?

• While reliability is concerned with the accuracy of

boundaries of the research?
This is sometimes called external validity

Credibility – is the research trustworthy?
Validity – is the research design capable of
answering the question?
Reliability – is the research repeatable with
Transferability – can the findings be used in
Triangulation – involves examining the topic
with different methods
