The all-possible subset approach is recommended as an alternative over stepwise methods for selecting the best set of predictor variables for multiple regression. Several criteria are available for selecting the best subset model. These are compared with the principal component regression (PCR) method to investigate their usefulness for subset…

The purpose of this paper was to research published validity reports of the Multiple Assessment and Program Services (MAPS) Test and to conduct quantitative analysis on the validity coefficients from the MAPS reports to determine the generalizability of the results and to identify which variables in the reports impact these coefficients. The…

The basic purpose of the study was to determine the types and frequency of nonshorthand errors on typewritten transcripts of shorthand dictation of 40 intermediate and 34 advanced stenography students at the University of Missouri in 1970-71. (Author)

Although there is extensive literature on interpersonal influence in counseling, there are few studies of the relative influence of counselors on clients and clients on counselors. To investigate the convergent validity of three statistical approaches to relative influence in counseling, 57 counseling interviews were analyzed. The three…

Methods of regression commonality analysis are generalized for use in canonical correlation analysis. An actual data set (involving educators' attitudes toward death and age, locus of control, religion, and occupational role in working with terminally ill children) is employed to illustrate the extension. The method can be applied with respect to…

Current methods of obtaining reliability coefficients for mastery tests are laborious from a practitioner's perspective. Some methods require two test administrations; while others require access to computer facilities and/or advanced measurement and statistical procedures. This report provides tables from which practitioners can read such…

Revision of paper presented at the annual meeting of the American Sociological Association (Boston, 1968).

If the factor loadings of a core set of variables (fitting the general factor model) are the same when analyzed alone, and when analyzed along with the rest of the variables in an infinite behavior domain, there is only one factor variable in the domain that is a possible factor variable of the core set. If the condition of consistency of factor…

Graphic statistics as developed by John Tukey have some practical benefits for precision journalists as they assist in spotting trends not as easily noted without the use of nonparametric statistics. Some especially helpful graphic statistics are: "stem-and-leaf display,""box plots,""froots," and "flogs."…

A study was made of nine covariates as to their discriminating power between preschoolers who watch Sesame Street regularly and preschoolers who do not watch Sesame Street, Surveyed were 372 3-4 year old children on 9 variables. The nine variables were: race, socioeconomic status, number of siblings, child's birth order, maternal age, maternal…

Approximately 2,000 titles of journals and other periodicals which have published articles in the language sciences have been collected and examined. A determination has been made of the extent of their relevance to the language sciences. In addition, behavioral data identifying journals selected by linguists as those of greatest current interest…

In order to determine the number of credit hours being produced in various subject fields, questionnaires were sent to the institutions of higher education in the state of Colorado. This report presents tabular data on all resident classes taught at publicly controlled institutions, and on some taught at privately controlled institutions. The data…

As a first step in "improving and building up" the graduate program at the Wisconsin State University at Stevens Point, a study of graduate students was initiated in 1967. It examined the interrelationships of their graduate majors, undergraduate majors and colleges, high school deciles and class size, age, sex, level taught, geographic…

Researchers are often in a dilemma as to whether parametric or nonparametric procedures should be cited when assumptions of the parametric methods are thought to be violated. Therefore, the Kruskal-Wallis test and the ANOVA F-test were empirically compared in terms of probability of a Type I error and power under various patterns of mean…

Fixed-width confidence intervals for a population regression line over a finite interval of x have recently been derived by Gafarian. The method is extended to provide fixed-width confidence intervals for the difference between two population regression lines, resulting in a simple procedure analogous to the Johnson-Neyman technique.
