Three problems which arise in the analysis of data from natural classroom settings are examined. The effects of the use of different statistical procedures are illustrated with data derived from the 1969 Home Environment and School Study in Canberra. (Author/MLW)

Discusses how computational errors arise in analysis of data and how they can be minimized. Shows that all computations are subject to roundoff/truncation errors and how such errors are propagated and influence the stability and condition of a reaction. Applications to procedures used in analytical chemistry are addressed. (JN)

This article explores current attitudes, situations, and plans of improvement relating to discipline. Much of the data was obtained through research gathered from a junior high school, grades seven, eight, and nine, during the last school year. (Editor)

It was suggested that thought changes cognitions to be more consistent with one's initial attitude direction and, therefore, results in attitude polarization. Specifically, it was predicted that polarization would be highest under thought with reality constraints absent, followed by thought with reality constraints present, followed by…

This study attempted to shed light on the role of items cued to be remembered in the forgetting of items cued to be forgotten. (Author)

Assesses the effects of both experimenter- and subject-controlled reinforcement on the frequency of uncommon responses during originality training and a subsequent transfer task. (Author/RK)

In the context of the well-known fact that the higher stages of Kohlberg's sequence are less well-established than the lower, an exploratory investigation was carried out in a New Zealand teachers' college into the development of principled thinking in young adults and its association with various real-life experiences. (Editor)

The Mann-Whitney U Test provides an alternative to the parametric test when applied to the kinds of ordinal data typically generated by semantic differential and Likert-type scales. The application of this test to survey research problems in business education is discussed, and a computer program is given for the use by the business education…

Describes computer programs and projects designed to assist the chemical researcher in solving problems on-line. Discusses programs that interpret molecular structures, analyze multivariant data, and generate structural isomers of compounds. (MLH)

A review of data on parent-offspring resemblances in intelligence is presented in the context of correlation, regression and variance predictions from the polygenic model and an environmental model. (Editor)

This paper examines enrollment figures for blacks in colleges during the period 1940 to 1972 and develops a statistic that is more significant than either enrollment figures or percentages in order to determine the progress made by these students. (Author/AM)

This study has been an attempt to provide insight into the question of the influence of school resources on how well students perform academically. It examined the nature of the relationships between educational resources, socioeconomic and racial characteristics, and student academic performance in Florida. (Author/RK)

Article investigated the stability of both the Edwards Personal Preference Schedule (EPPS) (Edwards, 1959) and the Guilford-Zimmerman Temperment Survey (GZTS) (Guilford and Zimmerman, 1949) by presenting new data on the intercorrelations of the scales in these tests. (Author/RK)

Investigates memory capacity in rats for information about spatial location and provides information about some of the characteristics of the storage process used in this memory. (Author/RK)

The higher education community can now produce statistical data with which to support its demands to Washington. The data are compiled by the Policy Analysis Service (PAS) of the American Council on Education. Implications of this data availability are examined. (LBH)
