Educational and Psychological Measurement, v40 n2 p357-65 Sum 1980
Multiple-choice tests composed entirely of two-, three-, or four-choice items were investigated. Results indicated that number of alternatives per item was inversely related to item difficulty, but directly related to item discrimination. Reliability and standard error of measurement of three-choice item tests was equivalent or superior. (Author/CP)
