What evaluation method involves gathering data from multiple sources?

The evaluation method that involves gathering data from multiple sources is triangulation. Triangulation is a research strategy that enhances the credibility and validity of results by cross-verifying data from various sources or methods. This approach allows for a more comprehensive understanding of a phenomenon, as it minimizes the risk of bias that may stem from relying on a single source of information.

By integrating different perspectives, such as qualitative and quantitative data or insights from various stakeholders, triangulation builds a more robust and nuanced picture of the topic being studied. This process is particularly beneficial in educational settings, where the complexity of learning and teaching can be better understood through diverse lenses.

In contrast, correlation analysis focuses on quantifying relationships between variables rather than gathering data from multiple sources. Statistical sampling involves selecting a subset of a population for analysis, which does not inherently involve the use of various data sources. Focus group assessments typically provide qualitative insights from a specific group but do not encompass the broader data gathering method that triangulation represents.
