What is the primary purpose of triangulation in qualitative research?

• A. To enhance credibility of findings.
• B. To increase sample size.
• C. To avoid coding.
• D. To complicate the study.

Answer: (A)

Triangulation in qualitative research is a strategy for increasing the credibility of findings by cross-checking evidence from multiple angles. When you look at a phenomenon from different data sources, through different methods, by different investigators, or under different theoretical lenses, you can see whether the conclusions hold across these w separate vantage points. Converging evidence across these avenues strengthens trust that the interpretation reflects what’s actually occurring rather than a bias or artifact of a single method or perspective. There are several forms: data triangulation uses different sources or times; method triangulation uses multiple ways of collecting or analyzing data; investigator triangulation brings in more than one researcher to check interpretations; theory triangulation applies multiple theories to interpret the findings. For example, studying how a community experiences a health program might combine interviews, observations, and document analysis, with several researchers coding the data and interpreting it through different theoretical frames. If the themes align across these approaches, confidence in the results increases. That’s why the primary purpose is to enhance credibility of findings. It’s not about increasing sample size, avoiding coding, or making the study more complicated; rather, it’s about building a robust, well-supported understanding by demonstrating that findings persist across multiple avenues of evidence.
