This study examined the relationship between operating tax rates and selected socioeconomic variables for Illinois school districts. Districts were separately ranked by operating tax rates and then divided into four equal quartiles--low tax effort, low medium tax effort, high medium tax effort, and high tax effort. Discriminant analysis was used…

The utility of multiple discriminant analysis in predicting career interests in six specialities of engineering--aeronautical, chemical, civil, electrical, industrial and mechanical engineering--was studied. Freshman engineers at Purdue University were administered the Purdue Interest Questionnaire (PIQ). Multiple discriminant analysis was…

IN AN ATTEMPT TO BRIDGE THE GAP BETWEEN PSYCHOPHYSICAL STUDIES OF HUE DISCRIMINATION AND ETHNOLINGUISTIC STUDIES OF HUE LABELING, AN EXPERIMENT WAS CONDUCTED COMPARING LABELING AND DISCRIMINATION FUNCTIONS FOR SPEAKERS OF INDO-EUROPEAN (AMERICAN ENGLISH) AND NON-INDO-EUROPEAN (MEXICAN INDIAN) LANGUAGES. IT WAS FOUND THAT HUE LABELING PATTERNS OF…

A method is described by which cognitive structures in verbal data can be identified and categorized through numerical analysis and quantitative description. Transcriptions of interviews (in this case, the verbal statements of 40 researchers) are manually coded and subjected to analysis following the AaO (Agent action Object) paradigm. The texts…

A linear classification rule (used with equal covariance matrices) was contrasted with a quadratic rule (used with unequal covariance matrices) for accuracy of internal and external classification. The comparisons were made for seven situations which resulted from combining three data conditions (equal and unequal covariance matrices, minimal and…

The problem of interpreting the dimensionality underlying binary test data is addressed. Medical school students were tested on both achievement and aptitude measures. The person-by-test (aptitude) interaction matrix was factor-analyzed to identify patterns of individual differences. The resultant groups of similar patterns were used as the…

This report gives some simple examples of stability for one factor and 2 x 2 factorial analysis of variance, reliability and correlations. The findings are very different: from superstability (no transformation whatsoever can change the result) to almost total instability. This is followed by a discussion of applications to multivariate analysis,…

Various definitions of the term critical reading or critical thinking lead to the author's view that the definition of critical reading as discerning propaganda or checking the factual validity of a statement has been overemphasized. What is needed in content areas today is critical analysis, defined as a process that involves taking the printed…

The purpose of this study was to identify characteristics which describe high school dropouts. The investigation attempted to identify variables which would assist in differentiating persisters and withdrawals at Northeast High School in Kansas City, Missouri and in predicting dropouts at East High School on the basis of variable weightings drawn…

Discriminant analysis is reviewed in terms of: (1) formulations, (2) interpretations, (3) uses, (4) issues and problems in applications, (5) recent developments and conceptualizations, and (6) general references and computer programs. Four aspects of a discriminant analysis are considered. They are: (1) separation: determining intergroup…

This study demonstrates and discusses a new procedure for performing item analysis which utilizes multiple discriminant analysis to establish efficiently and effectively an index of item validity. Application of this statistical technique to data derived from an attitude survey of three groups of students enrolled in technical training courses…

The primary objectives of this paper are pedagogical: to provide a reliable semi-subjective transformation procedure that might be used without difficulty by beginning students in factor analysis; to clarify and extend the existing knowledge of oblique transformations in general; and to provide a brief but meaningful explication of the general…

Presented is a procedure that could be used by a school system to identify by the end of first grade those children who are likely to underachieve (achieve or overachieve) in reading by the third grade. The procedure consists of (1) Defining underachievers, achievers, and overachievers through use of regression and its standard error, (2)…
