This study investigates the relationships among factor correlations, inter-item correlations, and the reliability estimates of subscores, providing a guideline with respect to psychometric properties of useful subscores. In addition, it compares subscore estimation methods with respect to reliability and distinctness. The subscore estimation…

Divergent thinking (DT) tests are very often used in creativity studies. Certainly DT does not guarantee actual creative achievement, but tests of DT are reliable and reasonably valid predictors of certain performance criteria. The validity of DT is described as reasonable because validity is not an all-or-nothing attribute, but is, instead, a…

Six scoring methods for assigning weights to right or wrong responses according to various instructions given to test takers are analyzed with respect to expected change scores and the effect of various levels of information and misinformation. Three of the methods provide feedback to the test taker. (Author/CTM)

Students in an introductory college course (n=275) responded to equivalent 20-item halves of a test under number-right and formula-scoring instructions. Formula scores of those who omitted items overaged about one point lower than their comparable (formula adjusted) scores on the test half administered under number-right instructions. In contrast,…

A project is described that was undertaken to investigate: (1) how long a cloze test has to be to achieve optimum reliability without wasting anyone's time; and (2) how cloze tests should be scored in order to obtain maximum reliability. The literature recommended 50 deletions in order to provide for an adequate sample of examinee's abilities; it…

A study involving 105 sixth-graders examined three aspects of technical adequacy with respect to two general outcome measures in mathematics: the effects of aggregating scores and correcting for random guessing on reliability and validity and the extent to which the measures were sensitive to changes in performance. (Contains references.)…

The purpose of this study was to develop a testing method for the assessment of various types of writing at the elementary school level that would meet acceptable standards for educational measurement instruments as well as standards of utility and feasibility within a given educational system. The study was conducted within the framework of an…

The objective of this study was to show that standardized reading scores could be adequately estimated from scores on a criterion-referenced test in reading. This would reduce classroom test time, while, at the same time, provide the kinds of information teachers need to guide instruction, and the kinds of information administrators require for…

Technical improvements, which may be made in the reliability and validity of tests through confidence scores, are discussed. However, studies indicate that subjects do not handle their confidence uniformly. (MS)
