Statistical Extensions of Ponterotto and Ruckdeschel's (2007) Reliability Matrix for Estimating the Adequacy of Internal Consistency Coefficients
Abstract
The present article extends work on Ponterotto and Ruckdeschel's Reliability Matrix for estimating the adequacy of internal consistency measures. Specifically, it uses statistical tests to determine whether a calculated coefficient alpha is equal to or greater than the hypothesized population coefficient alpha identified in the Reliability Matrix. The Feldt, Woodruff, and Salih (1987) confidence interval test and Bonett's (2002) approximate z-test and N formula are applied. Select guidelines on reliability assessment and conducting statistical tests to determine adequacy of coefficient alpha are presented.

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.
