Assesses conditional states of item mastery found among items from different item domains and the effectiveness of various procedures for identifying such conditional relations. Item domains considered were from the curriculum area of multiplication of whole numbers, and were defined by a domain referenced testing system. (Author/RC)

Proposes three different multiple range tests based upon the Newman-Keuls philosophy with respect to significance levels. The three tests utilize the Fmax statistic, Cochran's statistic and a normalizing log transformation of the sample variances respectively. (Author/RC)

Judges holding divergent attitudes rated two sets of statements regarding uses of water reclaimed from sewage. Results showed a close linear relationship between item scale values obtained from positive and negative attitudinal groups, and a somewhat reduced rating range for judges holding unfavorable personal attitudes toward reuse. (Author/RC)

Because previous reports have suggested that the lowered validity of tests scored with empirical option weights might be explained by a capitalization of the keying procedures on omitting tendencies, a procedure was devised to key options empirically with a "correction-for-guessing" constraint.

A new item analysis index, e, is derived as a function of difficulty and discrimination to represent item efficiency. (Author/RC)

Overall findings were interpreted from a developmental perspective, and the data were shown to offer evidence for the contruct validity of the MSCA. (Author/RC)

Data from Terman's "Genetic Studies of Genius" (1925-1959) relating to sample size, mean IQ, and variance of IQ scores were analyzed in terms of their conformation to the theoretically projected statistics derived from a consideration of the normal curve. (Author/RC)

Univocal varimax is an orthogonal factor rotation strategy aimed at improving upon the simple structure qualities of a preliminary varimax solution. This is accomplished by targetting for patterned rotation the highest element in each row of the varimax factor loading matrix. (Author)

Methods for the path analysis of complex (i.e., not fully recursive) causal models are briefly discussed. A computer program which simplifies analysis of such models and provides an option for automatically deleting marginal paths is described. (Author)

Describes the rationale underlying as well as the major features of a computer-interactive APL program IRIS, the objective of which is to obtain an individual's simple ordering of a set of stimuli in as few paired comparison preference judgments as possible. (Author/RC)

INTERORD executes in the interactive mode by presenting pairs to be judged at a remote terminal. The respondent at the terminal judges which one of the objects dominates the other. INTERORD utilized the observed dominance relations to determine which additional relations are implied by the transitivity principle. (Author/RC)

A technique to measure and describe concisely a certain class of individual mental reasoning processes has been developed. The measurement is achieved by recording the complete dialog between a large, varied computerized information system with a broad range of logical operations and options and a human information seeker. (Author/RC)

A two-phase FORTRAN IV program called ITANA-III for an IBM 1130 computer is described that permits computation of psychometric characteristics of multiple-choice examinations including test statistics (phase I) and item statistics (phase II). Consisting of 280 statements, the program can handle up to 200 items with not more than 9 alternatives…

Describes a program system which was developed for the purpose of making estimates about the nature of the distribution of test scores which will result from an administration of a test composed of items of which estimates of item-difficulty and discrimination are available. (Author/RC)

Given judges' ratings on a set of variables, the program will produce for each variable, a printed analysis of variance summary table for between subjects/events, within subjects/events, and between judges sources of variability, a reliability coefficient, an adjusted reliability coefficient and means and standard deviations for each rater.
