The Correction for Guessing: A Case in Which Its Use Made Treatment Effects Appear Larger Than They Really Were.

Tallmadge, G. Kasten

Evaluation Review, v6 n6 p837-41 Dec 1982

Correction for guessing does not fulfill its intended function when test takers who have nothing to gain from scoring will respond randomly when they could have answered correctly had they tried. Raw scores underestimate abilities. If random guessing is more prevalent in the control group, correction for guessing inflates treatment effects. (Author/CM)
