Triangulation: Synthesis of Results from Multiple Data Sources for Evaluation and Decsion-making
An analytical approach known as “triangulation” integrates multiple data sources to improve the understanding of a problem and to guide programmatic decision-making to address such problems.
Whereas research seeks to definitively answer a pre-formed hypothesis, triangulation seeks to strengthen interpretations and improve decisions based on the available evidence.
As the information examined is collected by different methods, by different persons and in different populations, the findings can be used to corroborate data received from different sources, thereby reducing the effect of both systematic bias and random error that may be present in a single study.
