TYPES OF TRIANGULATION Denzin (1970) extended the idea of triangulation beyond its conventional association with research methods and designs. He distinguished four forms of triangulation: 1. Data triangulation, which entails gathering data through several sampling strategies, so that slices of data at different times and social situations, as well as on a variety of people, are gathered. 2. Investigator triangulation, which refers to the use of more than one researcher in the field to gather and interpret data. 3. Theoretical triangulation, which refers to the use of more than one theoretical position in interpreting data. 4. Methodological triangulation, which refers to the use of more than one method for gathering data.
