An investigation was undertaken of the intercorrelations among residuals obtained by applying regression techniques under two conditions: (1) mean sixth-grade Metropolitan Achievement Test reading scores predicted by mean second-grade Stanford Achievement Test reading scores, and (2) mean sixth-grade reading scores predicted by mean second-grade…

This study was designed to accomplish two interrelated objectives: first, to investigate the existing relationship between selected factors previously identified as being significant in attempting to predict military service losses during first-term service and second, to make available to qualified users a comprehensive data base for further…

The two purposes of this study were: (1) to identify those factors that significantly affect the use of the science process skill of prediction, and (2) to construct and test a probabilistic equation, based on a competence-performance model of cognitive development that accounts for a child's performance on tasks involving the skill of prediction.…

In this speech, the author discusses a study made that attempted to determine if there are differences in characteristics among school districts that implement full-scale models of year-round schools, districts that implement restricted models of year-round schools, and districts that do not implement any year-round model. Concurrently, he…

Measures of background characteristics, school performance, and test achievement were analyzed for four race-by-sex samples of third graders who were known to have later become high school dropouts. In each sample, age in the third grade, course marks, and standardized achievement scores were found to be significantly related to the grade in which…

The study attempted to demonstrate significant relationships between systematically derived occupational descriptors and selected measures of worker characteristics in the affective domain. The predictor variables were derived from the Occupation Analysis Inventory (OAI) and consisted of work-dimension scores describing occupations in terms of…

As with any new theory, it is necessary to validate the basic construct of vocational maturity. Once this is done, instruments to measure vocational maturity, or decision making, can be evaluated. With this as an objective, this paper discusses some of the problems associated with measuring vocational maturity, such as identifying variables,…

The relative power of three possible experimental designs under the condition that data is to be analyzed by nonparametric techniques; the comparison of the power of each nonparametric technique to its parametric analogue; and the comparison of relative powers using nonparametric and parametric techniques are discussed. The three nonparametric…

The feasibility and effectiveness of a Bayesian method for estimating regressions in m groups is studied by application of the method to data from the Basic Research Service of The American College Testing Program. Evidence supports the belief that in many testing applications the collateral information obtained from each subset of m-1 colleges…

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 assumption that the learning of letter names in their proper sequence is a prerequisite for literacy can be questioned. There is disagreement over the value of early letter-name training. It is variously said to aid in letter or word discrimination, to aid in attaching sounds to letters, and to interfere with both of these tasks. An analysis…

A study was conducted to determine whether six personality variables, presently used in admissions decisions by a nursing school, were effective predictors of success on the State Board Examination (SBE), the nursing licensing examination. The personality variables were measured by subtests of the Personal Preference Schedule of the Psychological…

Prose passages read aloud or silently were rated for pronounceability and comprehensibility. The relationships of text-derived readability indices to reading rate, comprehensibility ratings and comprehension test scores were explored. Reading rate in syllables per minute was unrelated to readability. The high correlation between rate in words per…

This paper describes the method used by Tracz and Burtnyk for the estimation of future salary schedules in the Ontario secondary school system. The application of the algorithm to the Ontario secondary school system predicts a possible breakdown in the fixed step salary schedule at about 1980. This situation results primarily because of the…
