Effects of Subject and Rater Characteristics on the Accuracy of Visual Analysis of Single Subject Data.
Richards, Stephen B.; Taylor, Ronald L.; Ramasamy, Rangasamy
Psychology in the Schools, v34 n4 p355-62 Oct 1997

Results indicate visual analysis accuracy was less than chance. Rater and student characteristics largely did not affect the ratings. (RJM)
