Eight different methods are reviewed for determining whether two or more tests are equivalent measures. These methods vary in restrictiveness from the Wilks-Votaw test of compound symmetry (which requires that all means, variances, and covariances are equal), to Joreskog's theory of congeneric tests (which requires only that the tests are measures…

The theme of this first lesson is the distinction between the simple present (e.g. He eats lunch every day.)…

When repeated measures are obtained on the same subjects, interobservation dependencies frequently are generated. The major ways in which these dependencies can arise are illustrated and it is shown how these dependencies may invalidate the use of analysis of variance (ANOVA) and its extension, trend analysis, as methods of evaluating the data of…

Increased student demand for foundations courses, coupled with a lack of qualified staff, made it necessary to provide workable alternatives to traditional instruction. Substantial adjustments could not be made until the efficacy of the new methods could be documented. The study compared cognitive and attitudinal outcomes of two types of classes,…

A cubic spline method for smoothing equipercentile equating relationships under the common item nonequivalent populations design is described. Statistical techniques based on bootstrap estimation are presented for choosing an equating method/degree of smoothing. Smoothing decreases the estimate of random error but results in an increase in…
