Simulating Statistical Power Curves with the Bootstrap and Robust Estimation

Simulating Statistical Power Curves with the Bootstrap and Robust Estimation

Access: Use of this item is restricted to the UNT Community.
Date: August 2001
Creator: Herrington, Richard S.
Description: Power and effect size analysis are important methods in the psychological sciences. It is well known that classical statistical tests are not robust with respect to power and type II error. However, relatively little attention has been paid in the psychological literature to the effect that non-normality and outliers have on the power of a given statistical test (Wilcox, 1998). Robust measures of location exist that provide much more powerful tests of statistical hypotheses, but their usefulness in power estimation for sample size selection, with real data, is largely unknown. Furthermore, practical approaches to power planning (Cohen, 1988) usually focus on normal theory settings and in general do not make available nonparametric approaches to power and effect size estimation. Beran (1986) proved that it is possible to nonparametrically estimate power for a given statistical test using bootstrap methods (Efron, 1993). However, this method is not widely known or utilized in data analysis settings. This research study examined the practical importance of combining robust measures of location with nonparametric power analysis. Simulation and analysis of real world data sets are used. The present study found that: 1) bootstrap confidence intervals using Mestimators gave shorter confidence intervals than the normal theory counterpart ...

Southwest Texas Junior College: Organizational transformation along the border.

Southwest Texas Junior College: Organizational transformation along the border.

Date: December 2005
Creator: Thomas, Christopher James
Description: This study sought to identify components of the institutional transformation of Southwest Texas Junior College from its participation in the Rural Community College Initiative (RCCI) The RCCI was centered on increasing access to educational opportunities and regional economic development in four historically poor regions of the United States. It was felt that this two-pronged approach to increase access and economic development would ameliorate poverty and provide opportunity. The pilot colleges were chosen from Appalachia, Delta South, Northern Plains (Tribal colleges), and the Southwest. Southwest Texas Junior College in the southwest border region of Texas and Mexico was chosen in 1994 as one of nine pilot college participants in the Ford Foundation project. Documentation of the college's characteristics were conducted during the 1994 and 1995 preliminary visits by Stephen G. Katsinas at the request of the Ford Foundation to find suitable rural community colleges in historically distressed areas of the United States to be invited to participate in RCCI. Follow-up site visits were conducted by Christopher Thomas in 2002, 2004, and 2005. Data was collected during all site visits by open-ended questionnaires, interviews, content analysis of documents, and observation. Extended site visits and living in the college's residence halls increased the ...

Speaking up-speaking out: What does it take to prepare early childhood professionals to advocate for children and families?

Speaking up-speaking out: What does it take to prepare early childhood professionals to advocate for children and families?

Date: December 2002
Creator: Brunson, Mary Nelle
Description: The early childhood profession regards advocacy as a professional and ethical responsibility yet little is known about advocacy instructional practices in teacher education programs. This study surveyed selected early childhood teacher educators who currently prepare undergraduate preservice professionals in two- and four-year institutions throughout the United States to identify and evaluate the existing advocacy training practices in preservice education. The study was designed to: (a) determine what leaders in the field of early childhood believe constitutes appropriate advocacy training for preprofessionals, (b) describe the advocacy activities of teacher educators, (c) determine if there is a difference in the advocacy instructional practices of two- and four-year institutions, and (d) recommend a model for advocacy in preprofessional programs. The participants included 607 teacher educators who responded to a mailed questionnaire and 14 leaders of early childhood professional organizations who participated in telephone interviews. Participants represented 48 states and all geographic regions of the United States. Results indicate that teacher educators and leaders believe advocacy instruction is important in preparation programs. The most frequently included advocacy activities are professionalism and understanding the professional role. Advocacy skills and strategies focused on public policy were included the least. Findings show that teacher educators participate in ...

A structural equation model of contributing factors to adolescent social interest

A structural equation model of contributing factors to adolescent social interest

Date: August 1999
Creator: Craig, Stephen E.
Description: The focus of the present study was to test through SEM the relationships between family influences (FI) and school influences (SI) on factors hypothesized to be associated with adolescent social interest: school belonging (SB), extracurricular participation (EP), and peer/romantic involvement (PRI). The final model consisted of FI and SI that contributed to the expression of adolescent social interest. FI included parental communication and parental caring. SI consisted of teacher fairness. SB consisted of a child's self-reported feelings of belonging at school, EP included self-reported involvement in sports or academic clubs, and PRI consisted of self-reported desire for romantic involvement or desire for participation with others. The proposed model suggested that FI contributed significantly to self-reported SB, EP, and PRI. Additionally, it was hypothesized that SI would contribute significantly to SB and EP, but not to PRI. The data used in the current study were part of an existing data set collected as part of the National Longitudinal Study on Adolescent Health. The total sample size for the present study was 2,561 male and female adolescents aged 12-19 years. The data consisted of adolescent and parent self-report information. Results suggested a significant relationship between FI and self-reported SB and PRI. As ...

Student Outcomes in Selected Distance Learning and Traditional Courses for the Dallas County Community College District: A Pilot Study

Date: December 2004
Creator: Borcoman, Gabriela
Description: The study compared outcomes for distance learning courses with those of traditional courses offered by the seven campuses of Dallas County Community College District (DCCCD). The course outcomes were defined as completion rate, dropout rate and success rate. Eleven courses offered during the fall 2003 semester were selected for the study. The methods of instruction employed for each course were traditional classroom lecture/discussion and distance learning formats of Internet, TeleCourse and TeleCourse Plus. Internet courses are delivered on-line, using Internet access and a browser, TeleCourse uses one-way videos or public broadcasting, and TeleCourse Plus is a hybrid between Internet and TeleCourse courses. Seven of the courses selected were part of the core curriculum approved by Texas Higher Education Coordinating Board (THECB) while four other courses were completely transferable. Two types of specific data were extracted: course data and individual student data. Course data included method of instruction, length of course, instructor's load, enrollment, number of withdrawals, and grade distribution. In addition, course requirements including the use of email, videos and Internet, orientation and testing on campus were added as variables. The student data included demographic variables such as age, gender, ethnicity, family status, employment and academic variables including number of ...

Student services in Bible colleges and universities accredited by the Accrediting Association of Bible Colleges (AABC)

Student services in Bible colleges and universities accredited by the Accrediting Association of Bible Colleges (AABC)

Date: May 2000
Creator: Rogers, Kathi L.
Description: This study attempted to determine the types, extent, and quality of student personnel services in colleges and universities accredited by the Accrediting Association of Bible Colleges (AABC). The Basic Services Questionnaire (BSQ) was adapted for use among Bible colleges and universities and mailed to chief student affairs officers representing 69 Bible colleges in the United States accredited by the AABC. Of the 71 surveys mailed (two institutions employed both a Dean of Men and Dean of Women), 46 were returned for a response rate of 65 percent. Chi-square tests of goodness-of-fit were performed on the data in order to categorize the types, extent, and quality of student services provided by the institutions. The Mueller-Schuessler Index of Qualitative Variation was used to determine the homogeneity, or heterogeneity, of the chief student affairs officers when grouped according to specific variables (gender, ethnic origin, major for highest degree earned, and highest degree earned). Frequency counts and percentage distributions were used on demographic data to present a profile of chief student services administrators at AABC schools. The results of the study point to four conclusions. First, the types of student personnel services provided by American Bible colleges and universities accredited by the AABC closely ...

A Study of Department Chairs in Two-Year Colleges: A Comparison of the 1992 International Community College Chair Survey to Department Chairs in the North Texas Community College Consortium

A Study of Department Chairs in Two-Year Colleges: A Comparison of the 1992 International Community College Chair Survey to Department Chairs in the North Texas Community College Consortium

Date: August 2003
Creator: Gallagher, Judith
Description: A study was conducted to gather information from department chairs serving in the 26 two-year colleges that are members of the North Texas Community College Consortium using the International Community College Chair Survey (ICCCS). The ICCCS is designed to gather insights into four aspects of the chairs' professional lives: personal characteristics, responsibilities challenges, and strategies. The study compared the demographic data and the respondents' perceptions of the challenges their units will face in the next 5 years to the original survey conducted in 1992. The regional sample included 616 first-line administrators, and a 30.5% response rate was achieved. The demographic distribution of the regional respondents shows significant shifts in gender, age, education, experience and release time but constancy in race and stability of the population. Similarities between the two samples exist regarding the challenges of maintaining program quality, providing technology, and managing financial issues. The regional sample expresses greater concern about the challenges of distance education, external accountability, and student matters.

A Study of Practices and Procedures used to Prepare Competent Group Leaders by Instructors in CACREP-Accredited Master's Level Group Courses

A Study of Practices and Procedures used to Prepare Competent Group Leaders by Instructors in CACREP-Accredited Master's Level Group Courses

Date: August 2002
Creator: Simpson, Christopher S.
Description: This study identified the practices and procedures of instruction that is being implemented by group counseling instructors at CACREP-accredited institutions. A survey questionnaire developed by the researcher was used to gather data from 160 CACREP-accredited counseling units across the United States. The survey was designed to collect input from group instructors on how the didactic, practicum, and experiential components of the master's level group course are being implemented. Three assumptions were made in conducting this study: 1.) The majority of master's level group instructors will report that they use a didactic component in preparing students to become effective group leaders, 2.) The majority of master's level group instructors will report that they use an experiential component in preparing students to become effective group leaders, and 3.) The majority of master's level group instructors will report that they use a practicum component in preparing students to become effective group leaders. The survey questionnaire and, consequently, the results were divided into the respective sections of didactic, experiential, and practicum. The results indicated that each of these components were utilized in the instruction of master's level group courses.

A Study of the Relationship Between the Levels of Self-Awareness within Students Enrolled in Counseling Practicum and the Measurements of Their Counseling Effectiveness

A Study of the Relationship Between the Levels of Self-Awareness within Students Enrolled in Counseling Practicum and the Measurements of Their Counseling Effectiveness

Date: August 2002
Creator: Abney, Paul C.
Description: Counselor self-awareness is considered an important aspect of counseling effectiveness according to the American Counseling Association and the American Psychological Association and in numerous studies and articles within the counseling literature. With the effort to improve the effectiveness of counseling practicum students comes the need to understand the relationship between effectiveness ratings and the levels of counselor self-awareness. Gestalt Therapy literature, and the development of the Personal Orientation Inventory (Shostrom, 1963) provided the working definition of self-awareness in this study. Research and evaluation are means for improving the correlation between students' characteristics in counselor training programs and their effectiveness as perceived by faculty and doctoral supervisors. The purpose of this study was to determine the effects of practicum students' ages and their levels of self-awareness upon counseling effectiveness as measured by faculty and doctoral supervisors in a university clinic setting. Twenty-nine students who were enrolled in four practicum classes were administered the Personal Orientation Instrument. Four faculty supervisors and eight doctoral supervisors were administered the Counselor Effectiveness Rating Scale (Myrick & Kelley, 1971). The instruments were administered in the tenth week of the counseling practicum semester. Analyses of the data revealed a statistically significant interaction between the older practicum students' ...

Survey of Texas Public Universities and University Systems Involvement in State Public Policy Making

Access: Use of this item is restricted to the UNT Community.
Date: August 2004
Creator: Wolf, David Fletcher
Description: This study investigated the perceptions of influential relationships between Texas public university presidents, university system chancellors, and state legislators. The study's purpose was to examine Texas public universities engagement in lobbying type behaviors and whether public policy is affected through interaction and communication with legislative leaders. Moreover, of importance for this study was to identifying if Texas public universities actively work to influence the Texas legislature and if lobbying behavior exists whether or not that behavior influences public policy formation within the Texas legislative process. Lastly, this study focused on perceptions dealing with the Texas statute prohibiting state governmental agencies, including public universities and university systems, from influencing legislation through use of state funds. The study was conducted in the winter of 2003 and had 29 president / chancellor respondents and 88 legislator respondents. Three survey instruments were developed by the researcher to determine Texas public university president, system chancellor, and state legislator perceptions and attitudes concerning lobbying type activities, influence, and state statute compliance. Data reported consist of percentages, t-Test of significance, and Cohen's d effect size measure. Results from the study show agreement between the groups in areas of activities utilized to influence the legislative process and actual ...
