Nonfunctioning Options: A Closer Look.
Cizek, Gregory J.; Robinson, K. Lynne; O'Day, Denis M.
Educational and Psychological Measurement, v58 n4 p605-11 Aug 1998
The effect of removing nonfunctioning items from multiple-choice tests was studied by examining change in difficulty, discrimination, and dimensionality. Results provide additional support for the benefits of eliminating nonfunctioning options, such as enhanced score reliability, reduced testing time, potential for broader domain sampling, and increased validity of score interpretation.
