Triangulation. Triangulation refers to the use of more than one approach to the
investigation of a research question in order to enhance confidence in the ensuing
findings. Since much social research is founded on the use of a single research
method and as such may suffer from limitations associated with that method or from
the specific application of it, triangulation offers the prospect of enhanced confidence.
Triangulation is one of the several rationales for MULTIMETHOD RESEARCH. The term
derives from surveying, where it refers to the use of a series of triangles to map out an
area.
