Measures of variability are successfully used in predictive modeling in research areas outside of education. This study examined how standard deviations can be used to address research questions not easily addressed using traditional measures such as group means based on index variables. Student survey data were obtained from the Organisation for…

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…

Single-score measures of intelligence are inadequate to predict performance on a programed instruction format. Guilford's model of the intellect accounts for three dimensions relevant to learner abilities. The content dimension refers to the kind of material involved, the product dimension to the kind of output required, and the process dimension…

Normative data reported by publishers of the California Achievement Test, the Comprehensive Tests of Basic Skills, and the SRA Assessment Survey were used to illustrate a procedure for specifying goals for Title I programs in terms of normal curve equivalent (NCE) gains. The procedure was based on the amount of growth reflected in student reading…

Arguments which suggest that improved prediction of multiple criteria can be achieved employing pattern scoring of responses, as opposed to conventional methods, are examined. Models for improving prediction of single and multiple criteria were examined. The findings are: (1) simple linear combinations of predictor variables perform as well…

Noting that accurate procedures for predicting reading ability in school settings are necessary for a variety of purposes, this paper reviews methods for predicting reading ability and presents a new, more precise model for use at the second grade level. First, the paper defines reading expectancy as an informed estimate of the level of reading…

This report presents results of follow-up surveys of students and parents who had been part of a 1986/87 study of transition experiences of deaf high school students. The report examines post-high school transition experiences including postsecondary education or employment outcomes. Most of the analyses are based on responses of 592 deaf youth…
