Item-Option Weighting of Achievement Tests: Comparative Study of Methods.

Downey, Ronald G.

Applied Psychological Measurement, v3 n4 p453-61 Fall 1979

This research attempted to interrelate several methods of producing option weights (i.e., Guttman internal and external weights and judges' weights) and examined their effects on reliability and on concurrent, predictive, and face validity. It was concluded that option weighting offered limited, if any, improvement over unit weighting. (Author/CTM)
