Triangulation refers to the reviewing of data collected through different methods in order to achieve a more accurate research. It is the means of avoiding the weaknesses and biases which would encourage confidence in the research findings. Triangulation allows researchers to collect qualitative and quantitative data from primary and secondary sources.eg.in a study to determine if parent prefers their child to attend a traditional high school, the researcher could use questionnaire, conduct interviews or using the reports published from the ministry. The term is derived from surveying, which refers to the use of series of triangle to map out an area.
Denzin (1978) and Patton (1999) identified four types of triangulation
1) Data triangulation, which involves the gathering of data through several sampling strategies, so that portions of data at different times and social situations, as well as on a variety of people, are gathered.
2. Investigator triangulation, which refers to the use of more than one researcher in the field to gather and interpret data.
3. Theoretical triangulation, which refers to the use of more than one theoretical position in interpreting data.
4. Methodological triangulation, which refers to the use of more than one method for gathering data
The concept of triangulation measures the behavior in the social and behavioral research world Rather than seeing triangulation as a method for confirmation or verification, qualitative researchers generally use this technique to ensure that research is prosperous, forceful far-reaching and well-developed.
