Using a Monte Carlo approach, comparison was made between traditional procedures and a multiple linear regression approach to test for differences between values of r sub 1 and r sub 2 when sample data were dependent and independent. For independent sample data, results from a z-test were compared to results from using multiple linear regression.…

Canonical correlation analysis is a powerful statistical method subsuming other parametric significance tests as special cases, and which can often best honor the complex reality to which most researchers wish to generalize. However, it has been suggested that the canonical correlation coefficient is positively biased. A Monte Carlo study…

This study examines the relative effectiveness of two means of analyzing the pre-test/post-test control group experimental design. Samples were randomly drawn from a standardized normal population and assigned to one of the four cells of the design. A set of experimental differences were induced in the post-test experimental cell. Each case was…

The oxygen profile procedure is a means of measuring the oxygen concentration at various locations in a basin. By dividing the surface of a basin into sections and then establishing sample points on the surface, at mid-depth, and near the bottom, a waste water treatment plant operator can measure and plot dissolved oxygen data which can be plotted…

There is a growing body of evidence indicating that people often overestimate the similarity between characteristics of random samples and those of the populations from which they are drawn. This paper: reviews studies that have attempted to determine whether the basic heuristic employed in thinking about random samples is passive and descriptive…

Monte Carlo studies explored the sampling characteristics of Cohen's d and three approximations to Cohen's d when used as average effect size measures in meta-analysis. Reviews of 10, 100, and 500 studies (M) were simulated, with degrees of freedom (df) varied in seven steps from 8 to 58. In a two independent groups design, samples were obtained…

This study attempted to determine if the differentiated achievement results for high questioning and low questioning instructional that emerged in a previous study would be replicated if student involvement were extended, as manifested in an increase in the number of student responses solicited.

This paper presents and discusses the results of an empirical study of value orientations of a sample of students entering three different programs of study at a college of advanced education. (Editor)

It was the purpose of this study to compare the concepts of reading given by children defined as "good" readers and "poor" readers. (Author)

The aim of our investigation was to see whether the previous findings of consistent social class differences in language usage held good when writing and not speech was the mode of communication and a more rigorous control was exercised over the influence of essay topic upon language. (Author)

The net effect of the conditions under which tests are taken was empirically investigated using the scores obtained by high school students on an English and a mathematics test. (Author/BB)

This document provides a ready source of information about water/wastewater sampling activities using various commercial sampling and flow measurement devices. The report consolidates the findings and summarizes the activities, experiences, sampling methods, and field measurement techniques conducted by the Environmental Protection Agency (EPA),…

This manual was developed for use at workshops designed to introduce operators to the fundamentals of sewage plant operation. The course consists of lecture-discussions and hands-on activities. Each of the lessons has clearly stated behavioral objectives to tell the trainee what he should know or do after completing that topic. Areas covered in…

This manual was developed for use at workshops designed to upgrade the knowledge of experienced wastewater treatment plant operators. Each of the sixteen lessons has clearly stated behavioral objectives to tell the trainee what he should know or do after completing that topic. Areas covered in this manual include: sewage characteristics;…

The major hypothesis of this article was that there will be a positive relationship between custodialism in teacher pupil control behavior and unfavorable student attitudes toward school. (Author/RK)
