Types of Triangulation
Denzin (1978) identified four basic types of triangulation:
* 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.
