Using multiple perspectives and multiple sources of data helps to enhance the validity of the study and
decrease investigator’s bias (Denzin, 1970). By definition, triangulation is a way to provide the intended multiple
perspectives, data sources and methods which in turn, may increase the validity of a study (Long, 2005; Thurmond,
2001). Therefore, in turn, triangulation gives the researcher kind of confidence in his/her findings and intensifies the
credibility of his/her work (Jick, 1979).
