The Trials and Tribulations of Applied Triangulation: Weighing Different Data Sources
Researchers employ triangulation to increase the validity of inference in qualitative and quantitative research. Leuffen, Shikano, and Walter have presented guidance as to which strategies to use when triangulating data sources. In this article, I explore how their findings can be translated for practical research purposes. I offer an illustrative application concentrating on the political power of traditional political authorities in Uganda and Tanzania. I analyze the status quo of political power and the preferred political power of traditional leaders. To triangulate, I use three sources: (1) constitutional-legal texts, (2) the Afrobarometer survey, and (3) in-depth interviews. I shed light on possible problems and analytical strategies for triangulation in practice, with a specific focus on convergence and divergence of sources.
