Holland, Paul W.
Journal of Educational and Behavioral Statistics, v27 n1 p3-17 Spr 2002
Examined two ways of measuring the gap between two cumulative distribution functions (CDFs), vertical and horizontal distance. Demonstrated how these two approaches can lead to contradictory conclusions about small changes in gaps using real data from the National Assessment of Educational Progress. (SLD)
