What does "triangulation" in qualitative research refer to?

Triangulation in qualitative research refers to the combination of different data sources to confirm findings. This method enhances the validity and credibility of the research results by cross-verifying information from various sources or perspectives. By integrating diverse data sources—such as interviews, focus groups, observations, or existing literature—researchers can gain a more comprehensive understanding of the phenomenon being studied. This approach helps to mitigate biases that may arise from relying solely on a single data source, ensuring a richer and more nuanced understanding of the research topic.

While the other options may indicate various methods or frameworks within research, they do not accurately define triangulation in qualitative research. The emphasis on utilizing multiple data sources to strengthen findings is what makes option B the correct answer.
