The present study examined the "better-than-average" (BTA) effect among secondary school students during 3 consecutive years. It was hypothesized that boys would overestimate their abilities relative to their classmates more than girls and that comparative evaluations of liking would be positively related to comparative evaluations of…

The consistency by which shared abilities are assessed on three intelligence tests was investigated. Instruments under consideration include: the Wechsler Intelligence Scale for Children-Revised, the Kaufman Assessment Battery for Children, and the Stanford-Binet Intelligence Scale-Fourth Edition. A list of shared abilities and the subtests…

Administered 1930s version of Pintner General Ability Tests: Verbal Series to 138 fifth grade students. Compared to scores from current intelligence and achievement tests, Pintner means were similar. Correlations of Pintner with other tests were of same order as those typically reported among contemporary measures. Item difficulty appeared similar…

The power of the procedure of W. Stout to detect deviations from essential unidimensionality in two-dimensional data was investigated for minor, moderate, and large deviations from unidimensionality using criteria for deviations from unidimensionality based on prior research. Test lengths of 20 and 40 items and sample sizes of 700 and 1,500 were…

The effects of reviewing items and altering responses on the efficiency of computerized adaptive tests and resultant ability estimates of the examinees were explored for medical technology students (220 students could and 492 students could not review and alter their responses). Data do not support disallowing review. (SLD)

As part of a larger project to assess changes in student learning resulting from school reform, this study equates levels 6 through 14 of the mathematics and reading comprehension components of Form 7 of the Iowa Tests of Basic Skills (ITBS) with levels 7 through 14 of the mathematics and reading comprehension components of the CPS90 (another…

The performance of the following four methodologies for assessing unidimensionality was examined: (1) DIMTEST; (2) the approach of P. W. Holland and P. R. Rosenbaum; (3) linear factor analysis; and (4) non-linear factor analysis. Each method is examined and compared with other methods using simulated data sets and real data sets. Seven data sets,…

The performance and career progression of a sample of 20,705 airmen were monitored throughout their initial tour of service. For comparative purposes, this sample was divided into high school graduate and nongraduate groups and further subdivided by Armed Forces Qualification Test (AFOT) mental categories. Points of comparison included:…

A two-stage testing strategy is one method of adapting the difficulty of a test to an individual's ability level in an effort to achieve more precise measurement. A routing test provides an initial estimate of ability level, and a second-stage measurement test then evaluates the examinee further. The measurement accuracy and efficiency of item…

The general intelligence factor (g) was investigated using 170 university students across three batteries of ability measures: (1) a short-term memory battery; (2) the Multidimensional Aptitude Battery; and (3) a reaction time battery. Results support the notion of g and suggest short-term memory as an essential aspect of intelligence. (SLD)

The stability of some dimensions of ability between the ages of 12 and 15 years was investigated for 225 boys and 242 girls in Sweden. Testing in grades 6, 8, and 9 indicated high stability for the general intelligence factor and for the residual of the General Visual factor. (SLD)
