Given a set of dichotomously scored items, ordering theory attempts to identify a hierarchy among those items. A graphic representation is presented for an empirically obtained hierarchy and a testing procedure to evaluate hypothesized hierarchical relationships. (Author/JKS)

A computer program for scoring written simulation tests provides individual scores and basic item analysis data. The program is written in Fortran IV and can accomodate up to thirty-five hundred options and up to ten thousand examinees. (Author/JKS)

Using 463 fifteen year old girls from five girls' schools in the metropolitan area of Sydney, this study examines four aspects of the Junior Eysenck Personality Inventory that has been subject to criticism, namely the terminology used in certain JEPI items, item response rate ceilings, factorial structure of the inventory, and the relationship…

This study compared the item difficulty, item discrimination, and test reliability of three forms of multiple-choice items: (1) one correct answer; (2) "none of the above" as a foil; and (3) "none of the above" as the correct answer. Twelve items in the three formats were administered in a college statistics examination. (BS)

This paper develops and applies three nonparametric comparisons of the shapes of two item characteristic surfaces: (1) proportional latent odds; (2) uniform relative difficulty; and (3) item sensitivity. A method is presented for comparing the relative shapes of two item characteristic curves in two examinee populations who were administered an…

The effects of statistical and cognitive difficulty ordering of test items, gender, and explicit labeling of item type on college students' test performance were assessed. A total of 137 male and 265 female undergraduates were administered two 40-item multiple choice tests. Results indicate significant effects for gender and use of labels, but…

An approximate relationship is devised between the unidimensional model used in data analysis and a multidimensional model hypothesized to be generating the item responses. Scale shrinkage is successfully predicted for several sets of simulated data. (Author/LMO)

A three subscale inventory designed by Fenigstein, Scheier, and Buss to measure self-consciousness was administered to 297 college students. Fenigstein et al.'s representation was found to fit the data in its original form. Items on the subscales differ nearly as much statistically as they do substantively. (Author/LMO)

Maximum likelihood procedures are presented for a general model to unify the various models and techniques that have been proposed for item analysis. Unconditional maximum likelihood estimation, proposed by Wright and Haberman, and conditional maximum likelihood estimation, proposed by Rasch and Andersen, are shown as important special cases. (JAZ)

The applicability of a new multiple-group factor analysis of dichotomous variables is shown and contrasted with the item response theory approach to item bias analysis. Situations are considered where the same set of test items has been administered to more than one group of examinees. (Author/BS).

The wording and structure of questionnaire items can interact with specified sample categories based on evaluation goals and respondent characteristics. The effects of the interactions can restructure samples and introduce bias into the data analysis. These effects, and suggestions for avoiding them, are demonstrated for five types of…

Analysis of 621 peer-peer items in the zero to six year age range from 54 assessment tests revealed such results as that over one-third of the items featured social participation, and that problems were found with the tests' ability to identify peer-peer deficits and to provide a framework for intervention. (MC)

The relationship between item parameter values obtained from independent Birnbaum (l968) model calibrations of the same item set from two different samples is examined. (Author)

DICOT, a computer program for the Rasch analysis of classroom tests, is described. Results are presented in a self-explanatory form. Person ability and item difficulty estimates are expressed in a familiar metric. Person and item fit statistics provide a diagnosis of individual children and identification of problematic items. (Author/DWH)

A procedure for determining the reliability of an examinee knowing k out of n possible multiple choice items given his or her performance on those items is presented. Also, a scoring procedure for determining which items an examinee knows is presented. (Author/JKS)
