An Analytical Procedure for the Equipercentile Method of Equating Tests

Prior use of the equipercentile method of test equating was based on a graphic procedure which is tedious, subject to smoothing errors, and non-analytical. Recognition of the equipercentile method as a curve-fitting procedure for two cumulative percentage distributions leads to a proposed analytical...

description	Prior use of the equipercentile method of test equating was based on a graphic procedure which is tedious, subject to smoothing errors, and non-analytical. Recognition of the equipercentile method as a curve-fitting procedure for two cumulative percentage distributions leads to a proposed analytical solution to the problem through use of linear estimates for successive "missing" score points. A complete equipercentile procedure which uses the proposed method and provides linear and quadratic functions for goodness-of-fit and extrapolation is discussed and illustrated with data from a test equating project. A FORTRAN IV program for the complete procedure is available. (Author)
