Triangulation of The Children of Sex-Workers in Bangladesh

Intercultural researchers usually use two types of investigation processes. First is quantitative research, which employs numerical indicators to ascertain the relative size of a particular communication phenomenon. The second type of investigation process is qualitative research, which employs symbols and words to indicate the presence or absence of phenomena or categorize them into different types. But professional and academic researchers tend to use triangulation techniques in their research investigations. Triangulation is a kind of `belt and braces`or insurance policy approach that’s used to try to counter the weakness that exist in different methods of data collection and analysis (Walsh, M.2001).In this study triangulation was employed to understand the process of problems and prospects of mainstreaming of CSW. Triangulation refers to the use of more than one approach to the investigation of a research question in order to enhance confidence in the ensuing findings. Since much social research is founded on the use of a single research method and as such may suffer from limitations associated with that method or from the specific application of it, triangulation offers the prospect of enhanced confidence. Triangulation is one of the several rationales for MULTIMETHOD RESEARCH (Bryman, A).

TRIANGULATION In social research, the term is used to refer to the observation of the research issue from (at least) two different points. This understanding of the term is used in qualitative as well as quantitative research and in the context of combining both. Triangulation is most often equated with applying different methodological approaches. The purpose of triangulation in qualitative research is to increase the credibility and validity of the results. Several scholars have aimed to define triangulation throughout the years.

• Cohen and Manion (1986) define triangulation as an "attempt to map out, or explain more fully, the richness and complexity of human behavior by studying it from more than one standpoint" (Cohen, L., & Manion, L. 2000).
• Altrichter et al. (2008) contend that triangulation "gives a more detailed and balanced picture of the situation" ( Altrichter, et al. 2008) .
• According to O’Donoghue and Punch (2003), triangulation is a “method of cross-checking data from multiple sources to search for regularities in the research data" (O'Donoghue, T., Punch K. 2003).

The idea of triangulation is very much associated with measurement practices in social and behavioral research. An early reference to triangulation was in relation to the idea of UNOBTRUSIVE METHOD proposed by Webb et al. (1966), who suggested, “Once a proposition has been confirmed by two or more independent measurement processes, the uncertainty of its interpretation is greatly reduced. The most persuasive evidence comes through a triangulation of measurement processes” (p. 3).
Here Methodological triangulation (Denzin 1970)is used, which refers to the use of more than one method for gathering data and ofcourse between-method triangulation involved contrasting research methods, such as a questionnaire and observation.
