In nursing research, triangulation refers to the use of multiple sources to validate findings by the nursing researcher. It involves the combination of both quantitative and qualitative research methods within a single study. The term “triangulation” has its roots in modern mathematics and can be traced back to the Ancient Greeks. It is found in the field of navigation and facilitates the concept of determining an unknown point by means of knowing the location of two known points. This mixed-method or multimethod research in nursing research refers to the ability to strengthen a study design by the use of two or more research designs, thus increasing a researcher's ability to interpret findings. The most common being the combination of qualitative and quantitative research.
