The present paper contributes to research methodology as practiced in the field by providing practitioners with a concise statement of the problems in analyzing unbalanced designs, and by clarifying the conditions under which the analysis alternatives are most appropriate. The purposes of the present paper are: (1) to examine the analysis…

Studies pertaining to community growth have dealt with the community's territorial expansion, economy, government's functions, and institutions. Since researchers usually use the dimension that they have been taught (economists use economic measures, and social scientists use sociological measures), two problems have resulted: (1) How should…

The influence of an individual's cognitive style on hypothesis testing behavior was investigated. Thirty analytic and 30 global subjects each solved 24, 16-trial problems with intermittent reinforcement, i.e., E said "right" or "wrong" after every fifth response. Results indicated that the analytic subjects solved more problems…

This pamphlet contains a series of studies that grew out of the parent education project of the Institute for Development of Human Resources. The objectives and general design of the project consisted of instruction of 200 environmentally disadvantaged mothers by parent educators using a sequence of infant stimulation exercises conducted in the…

This regression system is an intermediate result of a project to develop a comprehensive regression computer system as a foundation for a complete statistical man-machine interface. The outstanding features of the system can be condensed into two principal concepts. First, the program dynamically allocates core resulting in no limits on title…

A study was conducted to (1) Analyze the context, structure, and performance of two community junior colleges in Florida, and (2) Determine the extent that the relationships established were consistent with Hage's axiomatic theory of organizations and Pugh's multivariate analysis of 52 organizations. A survey of authoritative literature and…

An investigation was made of influence in 77 academic departments of 11 community colleges in Maryland. The purposes of the investigation were to examine the relationship of perceived measures of influence to member attitudes of (a) policy agreement, (b) superior-subordinate relations, (c) peer relations; to examine the aslopes of the distribution…

In most behavioral science research very little attention is ever given to the probability of committing a Type II error, i.e., the probability of failing to reject a false null hypothesis. Recent publications by Cohen have led to insight on this topic for the fixed-effects analysis of variance and covariance. This paper provides social scientists…

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 principal objective of this study was to develop a classification system for the elements of student and teacher evaluative dialogue which would account for (1) the content area--task centered versus peripheral, and open versus closed; (2) psychological tone--accepting versus rejecting, and neutral versus judging; (3) possibility for…

The purpose of this study was to test the effects of an experimental method of instruction upon the cognitive development of disadvantaged first grade children. The hypotheses formulated were: (1) there is no difference between the medians of the control and experimental groups or between the numbers of subjects in each group placing at the…

Profiling, a procedure for evaluating methodological adequacy, a prerequisite for the acceptance or rejection of the conclusions of the investigation, is discussed. Three elements of this procedure are presented: (1) structuring of a logical argument, (2) generation of data and (3) analysis of data. All three elements are employed in hypothesis…

The effect of a structured program of musical training on the musical abilities of preschool children from disadvantaged environments was investigated. It was hypothesized that, if the musical abilities of such children could be improved sufficiently, they might then be able to enter elementary school on a level commensurate with that of their…

The technique of analysis of covariance is examined for its relevance to educational and psychological investigations. A study of the arithmetic procedures, history, and statistical properties shows that, though the concepts are relevant to many data collection designs, the customary calculations are often inappropriate. Some suggestions are made…

A study of twins was conducted to determine the presence of an hereditary component in short term memory and in three aspects of verbal divergent thinking--flexibility, fluency, and originality. Results showed the existence of a significant genetic component in the trait of short term memory, while none was found in verbal divergent thinking. (AG)
