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…

This investigation developed a methodology for adapting self-instructional materials to individual differences. Data on within-course variables of proportion of correct answers, latency and anxiety were monitored and regression analysis used to determine predictors of final performance. Regression equations were coded into the computer logic and…

This questionnaire is used in the Educational Quality Assessment Program in the State of Pennsylvania. It includes checklists for the following kinds of information from teachers: locale, stability, college, mother's education, father's occupation, attitudes relating to professional recognition, career interests, salary, length of service, and…

School unit residuals from multiple regression predictions of sixth-grade reading scores were developed for a population of 66 elementary schools, using Dyer's Method II (matched longitudinal data) and Method III (unmatched longitudinal data). The input variable sets were (1) previous achievement data alone, (2) achievement data and nonachievement…

The investigations focused on two main subject areas. The first series of experiments explored the validity of verbal association based inferences as an attitude measure and predictor of behavior. When compared with paper-and-pencil methods, the association based attitude index (EDI) showed high positive correlation as a group measure and medium…

Twelve learner characteristics and 26 demographic characteristics of entering preservice teachers were investigated to determine if the presumption of homogeneity was valid in relation to selected learner characteristics and to discover which, if any, demographic characteristics could serve as predictors of learner characteristics. The study also…

The Task Force on Undergraduate Admissions undertook in 1976 to determine: (1) what steps, if any, to take to participate the results of the California Postsecondary Education Commission study of the university's eligibility pool, which may show that the pool has grown larger than 12 1/2 percent in high school graduates; (2) what recommendations…

A Purdue University study of veterinary school students' first-year grade point averages in relationship to several variables concluded that in addition to traditional criteria, performance in specific preveterinary courses (in this case, 2-semester organic chemistry) and personality measures contribute to predicting success in veterinary school…

This paper discusses variables associated with student evaluation of teaching scores and comments on the use of multiple regression analysis as a tool for adjusting raw scores for factors essentially beyond the control of the instructor when ratings are used to reward teaching performance.
