Triangulation forms in qualitative research include which two forms?

• A. Data triangulation and methodological triangulation.
• B. Data triangulation and sampling triangulation.
• C. Instrument triangulation and theoretical triangulation.
• D. Temporal triangulation and cross-sectional triangulation.

Answer: (A)

Triangulation in qualitative research strengthens credibility by examining the same issue from multiple angles. The two forms commonly highlighted are data triangulation and methodological triangulation. Data triangulation means collecting information from different sources or at different times or in different places to see whether findings converge. For example, using interviews with participants, observations in the field, and relevant documents to look for consistent patterns. Methodological triangulation means applying more than one qualitative method to study the same topic, such as combining interviews with participant observation or with document analysis, so the interpretation is checked against different kinds of evidence. This cross-method check helps reduce bias that can come from relying on a single method. The other pairings described either mix concepts not typically grouped together as the primary triangulation forms or rely on time or sampling variations rather than distinct triangulation forms.
