Intraclass correlation reliability estimates are based on the assumption that the various measures are equivalent. Joreskog's (1970) general model for the analysis of covariance structures can be used to test the validity of this assumption. (For related document, see TM 002 301.) (Author)

Suggests a method of integrating user performance and attitudes toward the computer system into quality control procedures (QCP) and describes an application of user attitudes to the QPC in a class of novice computer users receiving instruction in BASIC programing language via formal classroom lecture with computer assisted instruction tutorials.…

Results of this study were interpreted in terms of the social control function served by the public schools. (Author/RY)

Describes a study of 39 Texas public elementary schools that investigated the effect of school climate and teacher characteristics on the cooperation between teachers and school library media specialists. The involvement of school librarians in instruction is discussed, and suggestions are offered for increasing their involvement. (33 references)…

A large number of national and geographic population samples were used to test the hypothesis that the variation in mean values of skin color in the diverse populations are consistently correlated with the mean measured or estimated IQs of the various groups, as are some other physical variables, known as an ecological correlation. Straightforward…

This exploratory study uses observations of the aggressive behavior of elementary school boys during three successive recess periods to test the hypothesis that aggressive behavior can spread between recess periods through peer contagion. If this hypothesis is correct, aggressive behaviors during the second recess period should mediate any…

This paper explores two related factors which influence variation in duration, prosodic structure and redundancy in spontaneous speech. We argue that the constraint of producing robust communication while efficiently expending articulatory effort leads to an inverse relationship between language redundancy and duration. The inverse relationship…

The authors investigated the relationship between students' ethnocultural person-environment (P-E) fit and college adjustment. They hypothesized differences between P-E fit of ethnocultural minority versus majority students at a predominantly White university but did not expect differences in adjustment. Furthermore, they explored the effects of…

The intent of the present study was to test for the validity and equivalency of a second-order factorial structure of the Beck Depression Inventory for and across three independent samples (n1=661; n2=239; n3=196) of nonclinical Swedish adolescents; the model under study derived from a cross-validated study of Canadian high school adolescents…

This study analyzed the enrollment of two computer classes at a public high school in northern Indiana to see if there was any computer inequity. The two classes examined--an introduction to computers course and a computer programming course--were studied over a period of four years. The sample consisted of 388 students in four years of the…

Several tasks were developed to investigate adolescents' ability to see correlations in data and to test hypotheses. Emphasis was placed on methodology: do students clearly understand the problem and do the tasks tap the skills they claim to? The 20 ninth-grade and 20 eleventh-grade boys and 15 college freshmen were tested. Most students did…

Utilizing data derived from the U.S. Census, a 10 percent stratified sample of U.S. population from nonmetropolitan counties (276 counties) as of 1950 was examined in terms of 2 opposing hypotheses: (1) the higher the level of manufacturing activity, the higher the quality of the housing in rural areas; and (2) industry attracted to rural areas…

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…

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…

A study is presented which attempts to investigate the interrelationships between certain assumptions about the nature of people held by the county extension leader, his sources of job satisfaction and dissatisfaction, and his performance of his function of leading the county staff. Data was collected by means of a questionnaire from 81 county…
