Identification and explication of construct relationships, under conditions of extraneous variable control in multiple regression and its multivariate analog, canonical analysis, were studied. Several data models were generated as a function of the interaction of partial correlation and orthogonal linear transformations on nursing examination…

A third followup survey within a National Longitudinal Study (NLS) of the high school class of 1972 finds that there is little difference in group variability in survey response when considering background characteristics, while significant differences in response rates are found when considering the group patterns of response to prior…

Evidence from a variety of sources suggests that systematic differences can be found in the ratings given to student essays as a function not only of the student's skills but also of aspects of both the student's background and the background of the rater. Additionally, the nature of the prompt which provided the central theme of the essay might…

The relative contribution of a variety of variables to different self-concept sub-constructs requires further exploration despite the existence of vast research about overall self-regard. The contributions of demographic, achievement, achievement motivation, and school self-concept dimensions to the prediction of the physical, moral-ethical,…

Results are presented of a study examining the Test of Integrated Process Skills (TIPS) and the Tobin and Capie Test of Logical Thinking (TOLT). Each of the two tests was analyzed to provide five subtest and total test scores, which were then correlated to examine relationships between broad measures of process skill and logical thinking ability…

A study designed to investigate the association between Piagetian cognitive and long-term mnemonic (recall and recognition) levels and problem solving in mathematics was conducted with 152 eighth-grade students. Cognitive level was determined by two evaluations (seven months apart) of a subject's performance on a clinically administered balance…

Studies have shown that sociopaths and alcoholics tend to come from similar social backgrounds and that they share several characteristics. To investigate the relationship between alcoholism and character disorder syndrome in adult males, 20 males who had a history of alcohol problems and displayed characteristics of character disorder were…

The leadership substitutes hypothesis has been used to explain the occasional successes and frequent failures of leadership predictions. Three hypotheses were formulated to test the viability of the leadership substitutes concepts. Questionnaires were administered to hospital managers (N=63) and engineers (N=71). Instrumental and supportive leader…

Thirty-one eight-year-old boys were the subjects of a study to determine the relationship between language skills in infancy and reading skills at elementary school age. As infants, the boys had been taped in interaction sessions with their mothers. The level of skill development of the infants was measured according to the principles of…

Guttman's facet theory is described as a method for quantifying information concerning attitudes. It is stated that attitude items are not negatively correlated for usual populations. An attitude is defined as a delimited totality of behavior with respect to something and its components are elements of a set. The first step in facet research…

The purpose of this study was to determine if a correlation existed between the classes of books checked out of the San Antonio College Library and the classes of books used in the Library. Data for out-of-library and in-library use were collected during February, 1978, and arranged by Dewey Decimal Classification (DDC) tens. By using the Pearson…

This Masters Thesis from the Ohio State University examines the trend in coverage of environmental problems in two newspapers from 1962-1977. Data were gathered by analyzing the content of the "Chicago Tribune" and "New York Times." Environmental stories from 24 selected issues per year were coded and analyzed using the…

Ridge regression is presented as an analytic technique to be used when predictor variables in a multiple linear regression situation are highly correlated, a situation which may result in unstable regression coefficients and difficulties in interpretation. Ridge regression avoids the problem of selection of variables that may occur in stepwise…

A continuing project titled "Measuring Career Readiness in Elementary Education" had as its fourth-year goal constructing learning activities to coordinate with six subtest areas of the Career Education Readiness Test (CERT). The secondary goal was to continue the refinement of the CERT through the analysis of data gathered during the…
