Definition. Triangulation involves using multiple data sources in an investigation to produce understanding. Some see triangulation as a method for corroborating findings and as a test for validity. This, however, is controversial.
Triangulation refers to the use of multiple methods or data sources in qualitative research to develop a comprehensive understanding of phenomena (Patton, ). Triangulation also has been viewed as a qualitative research strategy to test validity through the convergence of information from different sources.
Triangulation is a powerful technique that facilitates validation of data through cross verification from two or more sources. In particular, it refers to the application and combination of several research methods in the study of the same phenomenon. It can be used in both . Psychology Definition of TRIANGULATION: noun. 1. the procedure involved in confirming a hypothesis by gathering proofs from many sources or experiments or utilizing many processes.
Triangulation definition is - the measurement of the elements necessary to determine the network of triangles into which any part of the earth's surface is divided in surveying; broadly: any similar trigonometric operation for finding a position or location by means of bearings from two fixed points a known distance apart. A triangulation of the study results is a method applicable also to evaluation studies. Through a triangulation the researcher will acquire qualitative and quantitative data and the analysis of these increases the trustworthiness, or validity of the study.
