and qualitative studies as an alternative to traditional criteria like reliability and validity.


Purpose

The purpose of triangulation in qualitative research is to increase the credibility and validity of the results. Several scholars have aimed to define triangulation throughout the years. *Cohen and Manion (2000) define triangulation as an "attempt to map out, or explain more fully, the richness and complexity of
human behavior Human behavior is the potential and expressed capacity ( mentally, physically, and socially) of human individuals or groups to respond to internal and external stimuli throughout their life. Kagan, Jerome, Marc H. Bornstein, and Richard M. L ...
by studying it from more than one standpoint." *Altrichter et al. (2008) contend that triangulation "gives a more detailed and balanced picture of the situation." *According to O'Donoghue and Punch (2003), triangulation is a "method of cross-checking data from multiple sources to search for regularities in the research data."


Types

Denzin (2006) identified four basic types of triangulation:Denzin, N. (2006). ''Sociological Methods: A Sourcebook.'' Aldine Transaction. . (5th edition). *''Data triangulation:'' involves time, space, and persons. *''Investigator triangulation:'' involves multiple researchers in an investigation. *''Theory triangulation:'' involves using more than one theoretical scheme in the interpretation of the phenomenon. *''Methodological triangulation:'' involves using more than one method to gather data, such as interviews, observations,
