What is triangulation in qualitative research?

Triangulation involves using a combination of data or techniques to answer a research question. Triangulation can help you confirm the validity of your findings. This can be helpful in qualitative research, which is often subjective and vulnerable to bias.

Types of triangulation include the following:

  • Data triangulation: uses data from different sources
  • Investigator triangulation: has multiple people analyze data
  • Theory triangulation: uses different theoretical frameworks to analyze data
  • Methodological triangulation: uses different approaches to study the same phenomenon
