What does "generalizability" refer to in research findings?

Generalizability in research findings refers to the ability to apply the conclusions drawn from a study's sample to a broader population. This concept is critical because researchers often use a sample to make inferences about a larger group. For instance, if a study is conducted on a specific demographic segment, generalizability assesses whether the results are applicable to individuals outside of that group. High generalizability indicates that the findings are likely to hold true across various contexts and populations, enhancing the relevance and impact of the research.

By focusing on how findings can be extrapolated beyond the sample studied, researchers aim to ensure that their results are not only pertinent to the immediate study's subjects but also to the greater context they are investigating. This is essential for developing theories, applying interventions, and formulating policies that rely on insights generated from research.
