<![CDATA[AbstractTriangulation  is  the  application  and  combination  of  several research methodologies  in the study of the same phenomenon. It can be  employed  in  both quantitative(validation) and  qualitative(inquiry) studies, a method-appropriate strategy of founding  the credibility  of qualitative analyses,  becomes an alternative to " traditional criteria like reliability and validity"  and the preferred line in the social sciences.By  combining  multiple  observers,  theories,  methods,  and empirical  materials,  researchers can hope to overcome the weakness or intrinsic  biases  and the problems  that come  from single method, single-observer, single-theory  studies.  There  are  four basic  type  of triangulation:  data  triangulation,  involving time,  space, and persons; investigator  triangulation,  which  consist of the use of multiple, rather than  single  observers;  theory  triangulation,  which  consists of  using more  than  one  theoretical  scheme  in  the  interpretation  of  the phenomenon;  methodological triangulation, which involves using more than  one  method  and  may  consist  of  within-method  or  between- method strategies.]]>
