Investigating the distinction between submetropolitanization and decentralization of industry, the "Datafile for National Sample of Nonmetropolitan Counties" (a 10 percent national sample, involving 205 counties) was employed to test the following hypotheses: (1) the nearer the county to a Standard Metropolitan Statistical Area (SMSA), the higher…

The use of characteristic coding (dummy coding) is made in showing solutions to four multivariate problems using canonical analysis. The canonical variates can be themselves analyzed by the use of multiple linear regression. When the canonical variates are used as criteria in a multiple linear regression, the R2 values are equal to 0, where 0 is…

A study was designed to investigate the relationship between cognitive style and hypothesis testing strategies used in solving concept attainment problems. A field-independent (FI) and field-dependent (FD) cognitive style group of third grade students were administered concept attainment problems using a blank-trial methodology. The results…

An investigation was conducted of the characteristics of two estimation procedures and corresponding test statistics used in the analysis of completely randomized factorial experiments when observations are lost at random. For one estimator, contrast coefficients for cell means did not involve the cell frequencies. For the other, contrast…

Statistical methods that can be applied in the sequential analysis of multivariate empirical data are provided. Twenty-three specific formulas for use under varying conditions are discussed. A historical sketch of sequential analysis since World War II and a bibliography are included. (AE)

The effects of violation of the assumption of homogeneity of regression on the Type I error rate and on the power of analysis of covariance (ANCOVA) were investigated. The data situations included in the study involved two groups with one covariate and one criterion, with varying equal and unequal group sizes, and varying degrees of violation of…

The impact of "Misterogers Neighborhood" on nursery school children's prosocial behavior was assessed. Specifically, two hypotheses were tested: (1) that children who viewed several "Misterogers Neighborhood" programs would evidence more prosocial behavior than would nonviewers, and (2) that young viewers would show an increase…

This report reviews the objectives for coed housing, relates previous findings, and examines several hypotheses: (1) that coed units will have more activities and programs; (2) that the activities will be more widely varied; (3) that coed residents report more contact with faculty, more interaction with the opposite sex, more academically oriented…

An influential statistics test recommends a Levene text for homogeneity of variance. A recent note suggests that Levene's test is upwardly biased for small samples. Another report shows inflated Alpha estimates and low power. Neither study utilized more than two sample sizes. This Monte Carlo study involved sampling from a normal population for…

Comprehension of a problem or task that is generated in the real world rather than presented as a well-defined problem-statement of the kind encountered in textbooks or psychological laboratories was related to the ability of recognizing, selecting and formulating problems. The process of acquiring and utilizing this ability was conceptualized…

Compensatory education for disadvantaged preschool children includes, as one of its central components, a planned intervention program which is to provide the deprived child with linguistic skills comparable to those acquired naturally by children with a middle-class background. The hypothesis guiding the design and implementation of this study…

To study the effects of task and sample variation upon paired-associates (PA) performance, six third-grade and six sixth-grade classes in two urban schools were tested on two PA tasks, one pairing pictures of familiar objects (PA-CF), the other pairing nonsense syllables with Japanese "kanji" (PA-K). Hypotheses tested were: (1) Mean level of…

The logical structure of the Campbell and Fiske multitrait-multimethod approach is applied to the problem of studying growth and its determinants. The resulting model is a special case of Joreskog's general model for the analysis of covariance structures. The relationships of traditional psychometric formulations to this model are detailed.…

A new variant of the standard method for estimating the accuracy of educational tests is examined. It is found that the estimates produced by the new method are essentially unbiased and that the typical sizes of the errors of the estimates approach their theoretical lower limit as size increases, though they are still noticably above it for small…

This study proposes to explore characteristics not usually considered musical, and yet which might combine in persons in such a way that results may lead to a clearer understanding and more accurate measurement and prediction of musical talent. Two hypotheses were tested: (1) Musical talent can be predicted by means of a selected set of variables…
