Standard Errors of Equipercentile Equating for the Common Stem Nonequivalent Populations Design.

Jarjoura, David; Kolen, Michael J.

Journal of Educational Statistics, v10 n2 p142-60 Sum 1985

An equating design in which two groups of examinees from slightly different populations are administered a different test form with a subset of common items is widely used. This paper presents standard errors and a simulation that verifies the equation for large samples for an equipercentile equating procedure for this design. (Author/BS)
