Generalizability theory
open-in-new
<p>Generalizability theory, or G theory, is a statistical framework for conceptualizing, investigating, and designing reliable <a href="/facts/Observation/NTodmzCo">observations</a>. It is used to determine the <a href="/facts/Reliability_(statistics)/2QJrAeB5">reliability</a> (i.e., reproducibility) of measurements under specific conditions. It is particularly useful for assessing the reliability of performance assessments. It was originally introduced by <a href="/facts/Lee_Cronbach/M3YoPUIw">Lee Cronbach</a>, N. Rajaratnam, and <a href="/facts/Goldine_Gleser/IgEv4v8I">Goldine Gleser</a> in 1963. </p>
