Efficiency of Linear Equating as a Function of the Length of the Anchor Test.

Budescu, David

Journal of Educational Measurement, v22 n1 p13-20 Spr 1985

An important determinant of equating process efficiency is the correlation between the anchor test and components of each form. Use of some monotonic function of this correlation as a measure of equating efficiency is suggested. A model relating anchor test length and test reliability to this measure of efficiency is presented. (Author/DWH)
