TO DETERMINE CAUSAL FACTORS IN THE SUCCESS OR FAILURE OF SCHOOL BOND ELECTIONS, A STUDY WAS MADE OF SCHOOL BOND ELECTION RESULTS FROM 1960 THROUGH 1964 IN THE 209 IOWA SCHOOL DISTRICTS MAINTAINING A PUBLIC HIGH SCHOOL, JUNIOR HIGH SCHOOL, OR COMMUNITY COLLEGE. SEVENTY-NINE PERCENT OF THE REPORTING DISTRICTS (154 OF 195 TOTAL) SUCCESSFULLY PASSED…

A DISCUSSION WAS PRESENTED ON THE PROCEDURES OF EQUATING DIVERSE ABILITY SCORES OBTAINED BY DIFFERENT SCALED MEASURES. THE AUTHOR INDICATED THE NECESSITY OF EQUATING SUCH SCORES WHEN ABILITY IS TO BE TREATED AS A SINGLE INDEPENDENT VARIABLE IN SIGNIFICANCE TESTS AND IN COMPARATIVE ANALYSES OF DICHOTOMIZED GROUPS. A NEW RATIONALE FOR EQUATING…

Despite advances in common factor analysis, a review of 89 studies published in four selected journals between 1963 and 1976 indicated that behavioral scientists preferred principal components analysis, followed by varimax or orthogonal rotation. Resultant row sums of squares of factor matrices from principal component analyses of real data sets…

The intent of this investigation was to perform a validation study to determine whether RACE (Racial Attitude and Cultural Expression test) differentiates between primary grade students identified as having negative and positive attitudes. Students were categorized by a combination of administrator, teacher and clinical assessment into a negative…

Statistical methods are described for diagnosing and treating three important problems in covariate tests of significance: curvilinearity, covariable effectiveness, and treatment-covariable interaction. Six major assumptions, prerequisites for covariate procedure, are discussed in detail: (1) normal distribution, (2) homogeneity of variances, (3)…

The various costs of Type I and Type II errors of inference from data are discussed. Six methods for minimizing each error type are presented, which may be employed even after data collection for Type I and which minimizes Type II errors by a study design and analytical means combination.

The Rasch simple logistic model is used to examine the relative item parameter values of a personality inventory with respect to populations cross-classified by sex and country. While items conform to the model within each of the populations, half the items show significant discrepancies among the populations. (Author/RL)

Demonstrates a statistically valid method allowing students to explore randomization. Described are two examples: counting techniques for a small set of data and simulation for a large sample. (YP)

Reports the results of research that used descriptor subfiles in the online version of "MLA Bibliography" to quantify literary warrant in the domain of scholarly work about fiction. Topics discussed include domain analysis; the interaction between literary works, scholars, and library classification systems; and further research…

The general-information-theoretic approach was used to identify informational overlap and asymmetry between variables, using affective, cognitive, and behavioral measures. Using the chi-squared test, no significant differences were found in response rates, demographics, or patronage frequency of three stores between numerical (n=453) and graphic…

Discusses five common myths about statistical significance testing (SST), the possible erroneous and harmful contributions of SST to educational research, and suggested alternatives to SST for mathematics education research. (Contains 61 references.) (MKR)

Background: Childhood psychopathology is associated with both high and low levels of prosocial behaviour. It has been proposed that the development of prosocial behaviour shows emerging and consolidating individual differences as children grow older. The influences on these individual differences have not previously been examined in children and…

The purpose of this study was to investigate distance learning variables and their possible contributions to successful distance learning receptivity. The variables used in this study included gender, age, computer experience, learning style, and students taking an educational technology (EDTC) course and students taking a statistics (non-EDTC)…

This study examined correlations between teachers' attitudes toward mathematics/teaching mathematics and the practice of developmentally appropriate mathematics. This study tested two independent variables: (1) kindergarten teachers' attitudes toward mathematics; and (2) kindergarten teachers' attitudes toward teaching mathematics; and their…

Prevalence of severe sleep problems and its association with other variables were investigated with 109 individuals who have Angelman syndrome. Severe settling problems, frequent night waking, and early waking were found in 2%, 37%, and 10% of the individuals, respectively. Sleep problems were persistent in this sample. No statistically…
