NCME Instructional Module: Understanding Reliability.

Traub, Ross E.; Rowley, Glenn L.

Educational Measurement: Issues and Practice, v10 n1 p37-45 Spr 1991

The idea of test consistency is illustrated, with reference to two sets of test scores. A mathematical model is used to explain the relative consistency and relative inconsistency of measurements, and a means of indexing reliability is derived using the model. Practical aspects of estimating reliability are considered. (TJH)
