Measurement error in psychological research: Lessons from 26 research scenarios.
Abstract
technical principles to concrete research problems that appear in a wide variety of forms and with a myriad of obscuring features, details, and idiosyncracies. This article is based on a different approach: examination of a series of concrete research scenarios that we have encountered in our work as researchers, advisors to researchers, or reviewers. This article examines 26 real-world case studies and explicates them on the basis of the principles of reliability theory found in Cronbach (1947, 1951) and Cronbach et al. (1972). Although we cite and rely on these sources, other sources (e.g., Thorndike, 1951) would yield identical resolutions; only the terminology would be sometimes (slightly) different. In classical measurement theory, the fundamental general formula for the observed correlation between any two measures, x and y, is yields the dissattenuation formula:

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.
