THEORY OF GENERALIZABILITY: A LIBERALIZATION OF RELIABILITY THEORY†

Cronbach, Lee J., Rajaratnam, Nageswari, Gleser, Goldine C.·1963·British Journal of Statistical Psychology

Abstract

“Reliability theory” is reinterpreted as a theory regarding the adequac with which one can generalize from one observation to a universe of observations. If the observation is randomly sampled from the universe—whether or not the universe consists of equivalent observations—the intraclass correlation provides an approximate lower bound to the expected value of the desired coefficient of generalizability.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • G-theory offers a comprehensive analysis of the reliability and generalizability of assessment scores obtained from psychometric scales and identifies specific error sources potentially influencing measurements.

    “G-theory, a robust statistical methodology pioneered by Cronbach etal. (1963, 1972), offers a comprehensive analysis of the reliability and generalizability of assessment scores obtained from psychometric scales. It also identifies specific error sources potentially influencing measurements.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
