Triangulation refers to the use of multiple methods in a particular research project or evaluation. The idea here is that the limitations of one approach are compensated by the strengths of another in such a way that a more complete and informative picture emerges of the area being addressed. Liamputtong Rice and Ezzy (1999) neatly summarise four types of triangulation:
- Data Source Triangulation, involving multiple data sources, information should be elicited from all the different interest groups or associations involved with the project being evaluated.
- Methods Triangulation, combining varieties of methods such as focus groups, telephone surveys and in-depth interviews
- Researcher Triangulation, using a number of different researchers in the evaluation to provide different perspectives
- Theory Triangulation, which draws on a number of theoretical perspectives to provide new insights.
