Triangulation can be defined as a combination of different methods, study groups, local and temporal settings and different theoretical perspective in dealing with a phenomenon. It helps the researcher to describe and formalize the relationship between qualitative and quantitative research. It is also helpful for the researcher to promote the quality of qualitative research study.
It helps the researcher to maintain the authenticity and validity of research because it is a multi method approach. Triangulation is also helpful for the researcher to gather maximum data and information with minimum cost and time (Flick 2009).
There are four types of triangulation that are used by the researcher to accomplish a research study in effective manner such as data triangulation, investigator triangulation, theory triangulation and methodological triangulation. In order to accomplish this study, researcher has used two types of triangulation such as data and methodological triangulation.
These two types of triangulation help the researcher to analyze primary as well as secondary data and information for better results. Researcher chooses data triangulation because it refers to the use of different data sources such as books, articles, journals, newspaper, and personal experience etc. and data collected through different methods such as interviews and questionnaire (Crowther and Lancaster 2008). It helps researcher to analyze data and information that is related to the topic and find out conclusion and outcomes.
