The problem of spurious significance in multivariate exploratory research is discussed. When a very large number of statistical tests are performed, many tests will be significant on the basis of chance alone. To counter this problem, the use of two sign tests to analyze sets of results has been suggested; the chance expectation [CE test] assesses…

Develops a testing procedure based on a model including treatment effects on residual variances. (Author/RC)

The study assessed the general intellectual ability of Indian and Metis pupils of the Northwest Territory (N.W.T.), Canada. While minimizing cultural bias, an attempt was made to identify economical tests for this cultural group which would demonstrate (1) minimal loading on verbal and other culture-bound factors, (2) moderate relationship to…

Subjects are asked to answer six questions, partly with a frequency and partly by marking a verbally anchored scale with five categories. Some univariate and multivariate analyses are performed to elucidate the relations between variables with the two different modes of response. Although there are similarities in results for the two types of…

With the implementation of the all volunteer force concept, the Air Force must ensure that the objectively measurable range of ability in its manpower pool is being utilized. This is especially true for minority groups who have been categorized and channeled into military career areas based on their performance on two selection tests: the Armed…

This volume contains descriptions and statistical properties of test scales used with grade four through grade eight students in the National Longitudinal Study of Mathematical Abilities (NLSMA). Each scale is designed to measure a specified content or psychological area chosen as a dependent variable for the study. The scales are briefly…

This report presents the results, statistical analysis and implications of classification and attention training curricula field tested with Head Start children by their teachers. Teacher, location of program, and treatment were the variables considered but only treatment effects were significant. Results, summarized in three levels, indicate (1)…

In a previous study, (ED 038 175) Mississippi children, who were a year younger (3 1/2 to 4 1/2) than Alabama children, had scored higher than the Alabama children on posttesting. This supplementary report gives the results of further investigation of this finding. Explanations may be: (1) the younger children began with higher IQ scores; (2) more…

This monograph contains the third section, operations at the factor level, of a report of studies done in Helsinki, Finland, describing school achievement in terms of ability, trait, situational, and background variables. The report (1) investigates the structure of school achievement, (2) describes school achievement in terms of selected…

This paper presents a new multivariate index for use in educational planning. This new index, is called a propinquity index. An individual's propinquity index with respect to a given occupational group is his geometric distance in n-dimensional space from the group centroid, where each dimension is the standard score on one of the original…

This research investigated the interrelationships of educational decision making with the organizational climate and innovativeness in public schools. The data used in the study were gathered from 1,250 professional staff members in 49 public schools in Oregon, Washington, Nevada, Idaho, and Utah. The participating schools were classified into…

An attempt is made to explore the use of subjective probabilities in the analysis of item data, especially criterion-referenced item data. Two assumptions are implicit: (1) one wants to obtain a maximum amount of information with respect to an item using a minimum number of subjects; and (2) once the item is validated, it may well be administered…

The 1969 Invitational Conference on Testing Problems had as its theme "Toward a Theory of Achievement Measurement." Papers presented in Session I, The Nature of Educational Achievement, were: (1) "Concepts of Achievement and Proficiency" by William E. Coffman; (2) "The Functions and Uses of Educational Measurement" by Winton H. Manning; (3)…

Pearson's unrestricted chi-square procedure is reviewed, and an historical presentation of Neyman's restricted chi-square test is introduced with a discussion of its theory and applicability to education. An example of the Neyman procedure is discussed in detail to familiarize researchers with this useful technique for analyzing contingency…

Three topics in factor analysis are covered: a) a reliability coefficient for assessing the quality of a maximum likelihood factor analysis, b) an application of three-mode factor analysis to serial learning data, showing variations in learning curves over stages of learning and individuals, and c) the use of personal probability functions to…
