Bias and Precision of the Squared Canonical Correlation Coefficient under Nonnormal Data Conditions

Bias and Precision of the Squared Canonical Correlation Coefficient under Nonnormal Data Conditions

Date: August 2006
Creator: Leach, Lesley Ann Freeny
Description: This dissertation: (a) investigated the degree to which the squared canonical correlation coefficient is biased in multivariate nonnormal distributions and (b) identified formulae that adjust the squared canonical correlation coefficient (Rc2) such that it most closely approximates the true population effect under normal and nonnormal data conditions. Five conditions were manipulated in a fully-crossed design to determine the degree of bias associated with Rc2: distribution shape, variable sets, sample size to variable ratios, and within- and between-set correlations. Very few of the condition combinations produced acceptable amounts of bias in Rc2, but those that did were all found with first function results. The sample size to variable ratio (n:v)was determined to have the greatest impact on the bias associated with the Rc2 for the first, second, and third functions. The variable set condition also affected the accuracy of Rc2, but for the second and third functions only. The kurtosis levels of the marginal distributions (b2), and the between- and within-set correlations demonstrated little or no impact on the bias associated with Rc2. Therefore, it is recommended that researchers use n:v ratios of at least 10:1 in canonical analyses, although greater n:v ratios have the potential to produce even less bias. ...

Comparing outcome measures derived from four research designs incorporating the retrospective pretest.

Comparing outcome measures derived from four research designs incorporating the retrospective pretest.

Date: August 2007
Creator: Nimon, Kim F.
Description: Over the last 5 decades, the retrospective pretest has been used in behavioral science research to battle key threats to the internal validity of posttest-only control-group and pretest-posttest only designs. The purpose of this study was to compare outcome measures resulting from four research design implementations incorporating the retrospective pretest: (a) pre-post-then, (b) pre-post/then, (c) post-then, and (d) post/then. The study analyzed the interaction effect of pretest sensitization and post-intervention survey order on two subjective measures: (a) a control measure not related to the intervention and (b) an experimental measure consistent with the intervention. Validity of subjective measurement outcomes were assessed by correlating resulting to objective performance measurement outcomes. A Situational Leadership® II (SLII) training workshop served as the intervention. The Work Involvement Scale of the self version of the Survey of Management Practices Survey served as the subjective control measure. The Clarification of Goals and Objectives Scale of the self version of the Survey of Management Practices Survey served as the subjective experimental measure. The Effectiveness Scale of the self version of the Leader Behavior Analysis II® served as the objective performance measure. This study detected differences in measurement outcomes from SLII participant responses to an experimental and a ...

A Comparison of a Computer-Administered Test and a Paper and Pencil Test Using Normally Achieving and Mathematically Disabled Young Children

A Comparison of a Computer-Administered Test and a Paper and Pencil Test Using Normally Achieving and Mathematically Disabled Young Children

Date: May 1997
Creator: Swain, Colleen R. (Colleen Ruth)
Description: This study investigated whether a computer-administered mathematics test can provide equivalent results for normal and mathematically disabled students while retaining similar psychometric characteristics of an equivalent paper and pencil version of the test. The overall purpose of the study was twofold. First, the viability of using computer administered assessment with elementary school children was examined. Second, by investigating items on the computer administered mathematics test for potential bias between normally achieving and mathematically disabled populations, it was possible to determine whether certain mathematical concepts consistently distinguish between the two ability groups.

Comparison of Computer Testing versus Traditional Paper and Pencil Testing

Comparison of Computer Testing versus Traditional Paper and Pencil Testing

Date: August 2000
Creator: Millsap, Claudette M.
Description: This study evaluated 227 students attending 12 classes of the Apprentice Medical Services Specialist Resident Course. Six classes containing a total of 109 students took the Block One Tests in the traditional paper and pencil form. Another six classes containing a total of 118 students took the same Block One Tests on computers. A confidence level of .99 and level of signifi­cance of .01 was established. An independent samples t-test was conducted on the sample. Additionally, a one-way analysis of variance was performed between the classes administered the Block One Tests on computers. Several other frequencies and comparisons of Block One Test scores and other variables were accomplished. The variables examined included test versions, shifts, student age, student source, and education levels. The study found no significant difference between test administration modes. This study concluded that computer-administering tests identical to those typically administered in the traditional paper and pencil manner had no significant effect on achievement. It is important to note, however, that the conclusion may only be valid if the computer-administered test contains exactly the same test items, in the same order and format, with the same layout, structure, and choices as the traditional paper and pencil test. In ...

Comparison of evangelical Christian children's God-concepts and logical thinking ability.

Comparison of evangelical Christian children's God-concepts and logical thinking ability.

Date: May 2007
Creator: Penick, Starrla
Description: God-concepts of 24 third to sixth grade evangelical Christian children were compared with the children‘s logical thinking abilities in a mixed-method study. Measurements included the Children‘s Interview and the Group Assessment of Logical Thinking (GALT). God-concepts among the children were Biblical, comforter, communicates, creator, empowering, protector, provider, purposeful, human characteristics, lives in heaven, male, counselor, God is Jesus, all-knowing, loving, perfect, powerful, real, and parental. The majority of concrete thinkers conceptualized God as a gracious guide. The majority of transitional thinkers viewed God also as a gracious guide as well as a distant divinity. Implications were given for religious educators to develop a model for age-appropriate instruction and curriculum and to equip parents to promote spiritual development with children at home.

A Comparison of Knowledge/Skills Statements Needed by Teachers of Students with Emotional and Behavioral Disorders and Teachers in Juvenile Correctional Special Education Settings

A Comparison of Knowledge/Skills Statements Needed by Teachers of Students with Emotional and Behavioral Disorders and Teachers in Juvenile Correctional Special Education Settings

Date: December 1994
Creator: McArthur, Patrick L. (Patrick Lee)
Description: This study had a two-fold purpose. The first purpose was to compare the rankings of a set of knowledge/skills statements as reported by teachers of students with emotional behavioral disorders and teachers in juvenile correctional special education settings. A survey instrument designed to measure the importance, proficiency, and frequency of use of clusters of knowledge/skills statements was administered to 123 teachers in juvenile correctional special education settings in state institutions. Mann Whitney U analyses were calculated to compare the mean rankings of the two groups of teachers. The findings indicated that teachers in juvenile correctional special education settings and teachers of students with emotional and behavioral disorders were very similar as to which knowledge/skills clusters were important to their job performance, which clusters they were most proficient at using, and which clusters they utilized most frequently. The second purpose was to compare the teachers in juvenile correctional special education settings and to determine whether their mean rankings of the knowledge/skills clusters varied when analyzed by differing categories of age, type of certification held, years of teaching experience, and level of the teachers' education. Analysis of variance revealed no significant difference in the mean rankings in any of the comparison groups. ...

A Comparison of Three Criteria Employed in the Selection of Regression Models Using Simulated and Real Data

A Comparison of Three Criteria Employed in the Selection of Regression Models Using Simulated and Real Data

Date: December 1994
Creator: Graham, D. Scott
Description: Researchers who make predictions from educational data are interested in choosing the best regression model possible. Many criteria have been devised for choosing a full or restricted model, and also for selecting the best subset from an all-possible-subsets regression. The relative practical usefulness of three of the criteria used in selecting a regression model was compared in this study: (a) Mallows' C_p, (b) Amemiya's prediction criterion, and (c) Hagerty and Srinivasan's method involving predictive power. Target correlation matrices with 10,000 cases were simulated so that the matrices had varying degrees of effect sizes. The amount of power for each matrix was calculated after one or two predictors was dropped from the full regression model, for sample sizes ranging from n = 25 to n = 150. Also, the null case, when one predictor was uncorrelated with the other predictors, was considered. In addition, comparisons for regression models selected using C_p and prediction criterion were performed using data from the National Educational Longitudinal Study of 1988.
