Because, although the term ‘reliability’ is usually applied as a concept for testing or evaluating quantitative research, the idea is also used in all kinds of research.

This chapter discusses issues of the reliability and validity of our measuring instruments, and the reliability as well as the internal and external validity of our research as a whole.
