THIS PAPER DEALS WITH SOME TESTS OF HYPOTHESIS FREQUENTLY ENCOUNTERED IN THE ANALYSIS OF MULTIVARIATE DATA. THE TYPE OF HYPOTHESIS CONSIDERED IS THAT WHICH THE STATISTICIAN CAN ANSWER IN THE NEGATIVE OR AFFIRMATIVE. THE DOOLITTLE METHOD MAKES IT POSSIBLE TO EVALUATE THE DETERMINANT OF A MATRIX OF HIGH ORDER, TO SOLVE A MATRIX EQUATION, OR TO…

TO TEST THE APPLICATION OF THE GENERAL SYSTEMS APPROACH IN CURRICULUM DEVELOPMENT, A PROBLEM WAS PROPOSED IDENTIFYING THE PHENOMENA AND CONTINGENT VARIABLES OF THE CURRICULUM SYSTEM WITHIN THE INPUT-OUTPUT FRAMEWORK. WITH TEACHERS, SCHOOL ADMINISTRATORS, AND GRADUATE STUDENTS OF EDUCATION AS VOLUNTEER PARTICIPANTS, TWO EXPERIMENTAL GROUPS GIVEN…

The study of ability factors in young children has passed the stage of demonstrating that separate factors exist, the effort now being devoted to systematic identification of measurable abilities. This study was designed to confirm some of the tentative abilities demonstrated in other studies and to extend the exploration into memory processes and…

The effects of the violation of the assumption of normality coupled with the condition of multicollinearity upon the outcome of testing the hypothesis Beta equals zero in the two-predictor regression equation is investigated. A monte carlo approach was utilized in which three differenct distributions were sampled for two sample sizes over…

The technique originating from the study of ecological systems for the examination of dynamic educational systems over time is utilized. The technique is based on the theory of energy exchanges in interactions between variables. Using this technique, interactions among variables can be specified and simulated over time using an analog computer.…

Action research combines the development of competence with community action. It provides a means of organizing large numbers of people around well-defined, short-term jobs; engages people face to face with a problem; and translates research into politics by building a base of mass support for a given problem. The basic components of any action…

Following an analysis of work in the area of relationships between concept development and social development, a preliminary research project carried out to examine these relationships is discussed. Piaget's "The Language and Thought of the Child" served as a springboard for the past and present investigations. In the experiment…

In a multiple (or multivariate) regression model where the predictors are subject to errors of measurement with a known variance-covariance structure, two-sample hypotheses are formulated for (i) equality of regressions on true scores and (ii) equality of residual variance (or covariance matrices) after regression on true scores. The hypotheses…

A study was conducted to explore the interaction effects of self-esteem level and perceived program utility on the retention and cognitive achievement of adult basic education (ABE) students. A total of 200 black adult students receiving public assistance and enrolling in an ABE program with a reading level below 8.0 comprised the sample. Two…

This is one of a series of proxemic studies of dyadic communication behavior made by the authors in natural, academic and laboratory settings with the use of the DIAD. Based on the theory of anthropologists Hall (1966) and Birdwhistell (1970) and developed empirically as initial observations of dyadic interaction were made, the Dennis…

This research investigated the use of the Rasch simple logistic model in obtaining test-free ability estimates. Tests employing word, picture, symbol and number analogies were administered to college and high school students. The results show that the Rasch model does not offer an improvement over the use of percentile ranks in estimating…

The purposes of this study were to examine and evaluate the importance of three variables of Bloom's mastery learning model. The variables studied were specification of objectives, use of diagnostic-progress (d-p) tests, and use of alternate resources. The study used four seventh grade and four eighth grade classes; each grade classes were…

A study to investigate the effect of training in listening to speeded discourse on listening comprehension was conducted. Specifically, the study was designed to test the following hypothesis: There is no signifant difference in the amount of gain in listening achievement of the sixth-grade pupils who received speeded discourse speech training…

Hypothesizing that positive change in students' attitudes concerning leadership behavior would result from participation in a basic level five-week course at the National Outdoor Leadership School (NOLS), 80 student participants (16 years or older) were pre- and post-tested for attitudinal change. Using the Leadership Opinion Questionnaire (LOQ),…

Testing the hypothesis that group-centered leadership leads to less problem behavior among emotionally disturbed adolescents, 20 male and female adolescents aged 14-18 (from Karitas Community in Crystal Springs, Mississippi) were divided into leader-centered and group-centered groups and exposed to 3 weekend camping experiences. Assessments were…
