Using estimates of item ease and item discrimination, procedures are provided for computing estimates of the reliability and percentage of failing scores for tests assembled from these items. Two assumptions are made: that the average item coefficient will be approximately equal to the average of the estimated coefficients and that the score…

The Starkweather Target Game is designed to measure preschool children's willingness to try difficult tasks independent of ability. The game consists of a box-shaped target which responds, when the target is hit by a rolled ball, somewhat like a jack-in-a-box. When the bull's eye is hit, the lid opens and a surprise picture appears. After being…

The literature on criterion referenced testing is full of discussions concerning whether classical measurement techniques are appropriate, whether variance is necessary, whether new indices of reliability are needed, and the like. What appears to be lacking, however, is a clear and simple discussion of why the problems occur. This paper suggests…

The Phase 2 effort of a task to develop a new student critique form for the Air Training Command (ATC) is described. Phase 1 recommended the further development of group specific norms for officers, NCOs, and airmen enrolled in technical training schools. In Phase 2 additional items were added to the prototype form resulting in a later version of…

The Student Orientations Survey (SOS) is a research inventory designed to assess students' expressed attitudes regarding curricular-instructional policies, their views on preferred modes of learning, student-faculty roles, etc. The SOS provides a means of profiling students' general orientations toward various philosophies, purposes, and processes…

Five-hundred dichotomously scored response patterns were generated with sequentially independent (SI) items and 500 with dependent (SD) items for each of thirty-six combinations of sampling parameters (i.e., three test lengths, three sample sizes, and four item difficulty distributions). KR-20, KR-21, and Split-Half (S-H) reliabilities were…

This paper, a revision of the original document, "Correcting Partial, Multiple, and Canonical Correlations for Attenuation" (see TM 000 535), presents the formula for correcting coefficients of partial correlation for attenuation due to errors of measurement. In addition, the correction for attenuation formulas for multiple and cannonical…

The correction for attenuation formulas for partial, multiple, and canonical correlation coefficients are discussed and the effects of measurement errors on these statistics are explored. The notation is standardized and the derivation extended where appropriate. It is shown that as the reliabilities of the predictors become more disparate, the…

The problem of the comparability of change scores is investigated. Change quotients and residual change scores are evaluated as alternative approaches and methods for estimating the true change and true score residual, the reliability of change scores and residuals, and procedures for constructing confidence intervals for residuals are explored.…

Designed to investigate the performance of American Indian youth on the "Wechsler Intelligence Scale for Children" (WISC) compared to the "Chicago Non-Verbal" (CNV) for the purpose of establishing validity and reliability of the measurement and appraisal tools, this study analyzed test data from 71 Indian youth (aged 11 to 15)…

Major tenets summarizing Jensen's two-level theory of mental abilities were examined in a static-group comparison, correlational study. Caucasian siblings in grades one through four from low- and middle-socioeconomic (SES) populations were administered five Level I (associative learning ability) tasks and Raven's Progressive Matrices. Consistent…

Early procedures for the analysis of multivariate panel data do not rest on well-specified statistical models. Recent approaches based on path analysis suffer from the defects of variable standardization and lack of attention to measurement error. The paper formulates a measurement model for quantitatively scaled multivariate panel data. The model…

A set of Tests of Scientific Thinking were developed for possible use as criterion measures in research on creativity. Scores on the tests describe both quality and quantity of ideas produced in formulating hypotheses, evaluating proposals, solving methodological problems, and devising methods for measuring constructs.

The present study examined the reliability of the WISC-R subtests and IQ scales when administered to Mexican-American children. In an effort to extrapolate these findings to the individual child, this study also attempted to ascertain the standard errors of measurement for each subtest and IQ scale. (Author)

This paper presents two related studies describing the development and validation of the Teacher-Child Rating Scale (T-CRS), a brief objective socioemotional measure. Teachers rated K-6th graders on the T-CRS, and ratings were factor analyzed into three six-item problem and three six-item competence scales. (Author/LMO)
