Reliability is a concern every time a single observer is the source of data, because we have no certain guard against the impact of that observer’s subjectivity” (Babbie, 2010, p.158). In simple terms, if your research is associated with high levels of reliability, then other researchers need to be able to generate the same results, using the same research methods under similar conditions. It is noted that “reliability problems crop up in many forms.

Reliability refers to the extent to which the same answers can be obtained using the same instruments more than one time. Issues of research reliability and validity need to be addressed in methodology chapter in a concise manner.
