Random Guessing, Correction for Guessing, and Reliability of Multiple-Choice Test Scores
Frary, Robert B.; And Others
Journal of Experimental Education, 46, 1, 11-5, F 77
To date a theoretical basis has not been developed for determining changes in reliability when score points from random guessing are eliminated and those from non-randon guessing are retained. This paper presents a derivation of an expression for the reliability coefficient which displays the effect of deleting score components due to random guessing. Gives examples for hypothetical and real data. (Author/RK)
