Comparison of Methods for Computation and Cumulation of Effect Sizes in Meta-Analysis

Description: This study examined the statistical consequences of employing various methods of computing and cumulating effect sizes in meta-analysis. Six methods of computing effect size, and three techniques for combining study outcomes, were compared. Effect size metrics were calculated with one-group and pooled standardizing denominators, corrected for bias and for unreliability of measurement, and weighted by sample size and by sample variance. Cumulating techniques employed as units of analysis the eff… more

The Characteristics and Properties of the Threshold and Squared-Error Criterion-Referenced Agreement Indices

Description: Educators who use criterion-referenced measurement to ascertain the current level of performance of an examinee in order that the examinee may be classified as either a master or a nonmaster need to know the accuracy and consistency of their decisions regarding assignment of mastery states. This study examined the sampling distribution characteristics of two reliability indices that use the squared-error agreement function: Livingston's k^2(X,Tx) and Brennan and Kane's M(C). The sampling distri… more

A Comparison of Three Item Selection Methods in Criterion-Referenced Tests

Description: This study compared three methods of selecting the best discriminating test items and the resultant test reliability of mastery/nonmastery classifications. These three methods were (a) the agreement approach, (b) the phi coefficient approach, and (c) the random selection approach. Test responses from 1,836 students on a 50-item physical science test were used, from which 90 distinct data sets were generated for analysis. These 90 data sets contained 10 replications of the combination of three d… more

Cross-Cultural Validity of the Test of Non-Verbal Intelligence

Description: The purpose of this study was to investigate the extent to which a non-verbal test of intelligence, the Test of Non-Verbal Intelligence (TONI), may be used for assessing intellectual abilities of children in India. This investigation is considered important since current instruments used in India were developed several years ago and do not adequately reflect present standards of performance. Further, current instruments do not demonstrate adequate validity, as procedures for development and cul… more
