Scores within the chance range are differentiated, "uninterpretable" scores being those that demonstrate randomness (broadly defined) by failing to achieve typical levels of correlation with group-determined difficulty. The relevant literature is reviewed. Finally, randomness and uninterpretability are examined in light of the…

Functional-level testing is fundamental to the evaluation models of the Elementary Secondary Education Act Title I Evaluation and Reporting System, although criteria for determining what is a functional-level test are unclear. Reliability and validity of test scores in the range of chance is at issue. (Author/RL)

Responds to Fry's article in the January 1971 Reading Teacher, The Orangoutang Score." Suggests that chance level scores should not be assumed to have arisen only from random processes and that there are methods for identifying a thoughtful, nonrandom performance. References. (VJ)

On the basis of past research efforts to improve multiple-choice test information through differential weighting of responses to wrong answers (distractors), two statistical indices are developed. Each describes the properties of response distributions across the options of an item. Jaspen's polyserial generalization of the biserial correlation…

This study empirically determined the optimizing weight to be applied to the Wrongs Total Score in scoring rubrics of the general form = R - kW, where S is the Score, R the Rights Total, k the weight and W the Wrongs Total, if reliability is to be maximized. As is well known, the traditional formula score rests on a theoretical framework which is…
