2000-2001 Graduating Senior Survey:
Introduction, Methods, and Student Demographic Profile
(Report No. 2)

Introduction

This series of reports presents findings from the 2000-2001 Graduating Senior Survey at NC State. Students from all nine undergraduate academic units who graduated in December 2000 or May 2001 (AY00-01) are included.

This introductory report describes the survey�s methodology and provides a demographic profile of survey respondents in comparison to AY00-01 graduates. Specifically, it compares the gender, race/ethnicity1, and academic unit of survey respondents with those characteristics of the AY00-01 graduates. A separate report, "2000-2001 Graduating Senior Survey: All Respondents," focuses on each individual survey topic. Tables with gender and racial/ethnic comparisons, as well as comparisons between colleges, are available on the web.

Survey Methods

Students planning on graduating in December 2000 or May 2001 were eligible to complete the Graduating Senior Survey, which was available on the web or on paper. Those graduating with more than one major could complete a survey only for their primary major, as defined by university records. Academic departments were responsible for choosing through which mode - web or paper - their graduates would take the survey (41 departments chose the web option, and 11 the paper). Departments were also responsible for informing their students about the survey and for distributing the paper version of it. Both "web" and "paper" departments typically connected the survey to the Application for Degree process. Some departments choosing the paper option administered it in a required senior seminar or during an exit interview. Office of Institutional Planning and Research staff provided departments information to follow-up with non-respondents.

Respondents (Table 2-1)

Of the 3,254 students who graduated in Fall 2000 or Spring 2001, 2031 (62.4%) completed and returned usable surveys. Another 219 students returned surveys but are not included either because the student who had applied to graduate did not actually graduate (n=214) or gave incomplete information (n=5).

Overall, spring graduates were more likely than fall graduates to complete the survey2. When combining both Fall and December graduates, those asked to do the paper version of the survey had a slightly higher response rate than those asked to do it on the web.

Analyses

The data obtained from survey respondents were analyzed using standard statistical methods3. These reports attempt to provide a level of detail that makes the data more accessible and interpretable to the user. A primary purpose is to highlight patterns found in responses to related question items or between comparison groups. Such consistencies among items or between groups are usually more important for understanding the data than are the sizes of the differences between individual pairs of ratings or ranks or, to some extent, whether the differences are statistically significant. While some individual small differences might actually be statistically significant, they may not be substantively meaningful. On the other hand, when even relatively small differences yield consistent patterns within a similar series of questions, the results are potentially more telling.

The margin of error for the senior survey is low � under 1 percent (+0.82%) at a 95 percent confidence interval. That is, if 75.7 percent of the respondents said they would choose NC State again, we can be 95 percent sure that the true figure would be between 74.88 percent (75.7 - 0.82) and 76.52 percent (75.7 + 0.82) if all graduating seniors had responded to the survey4. The margin of error increases as the sample size decreases, so statements for various subgroups, such as the separate figures reported for whites and African Americans, are less precise than statements based on the total sample.

Demographics of the Senior Class and Survey Respondents

Gender and Race/Ethnicity (Table 2-2)

There are no significant gender or racial/ethnic differences between the AY00-01 graduating senior classes and those seniors who completed surveys. Women make up 43.3 percent of the senior class population, compared to 42.2 percent of the survey respondents. White students account for 84.4 percent of the senior population, 7.8 percent are African American, and 8.0 percent are other minorities. Among survey respondents, 84.9 percent are white, 6.8 percent African American, and 8.3 percent other minorities.

Demographics of the Senior Class and Survey Respondents by Semester of Graduation

Academic Unit (Table 2-3)

Table 2-3 shows enrollment of the combined AY00-01 graduating senior classes and survey respondents by academic unit. In general, colleges are accurately represented in the survey, with similar proportions of survey respondents and graduating class members. However, due to their relatively low response rates, College of Design and College of Textiles graduates are slightly underrepresented.

Endnotes:
1. The term "racial/ethnic" is used throughout these reports to recognize the potentially blurred distinction between the individual terms. In application materials studetns were requested to identify themselves using the following categories: Caucasian, African American or Black (not of Hispanic origin), Native American Indian or Alaskan, Asian or Pacific Islander, or Hispanic (Mexican, Puerto Rican, Cuban, Central or South American, or other Spanish origin or culture, regardless of race). For analysis purposes, these categories were collapsed into "White," "African American," and "other minorities."(back)
2. Most likely this was because this was the first time December graduates were included in the Graduating Senior Survey, and because the survey was not available until mid-September. (back)
3. In analyses not presented in these reports, responses were tested to determine whether there were significant differences between women and men, between white, African American, and other minority students, and between different colleges. Questions requiring categorical responses were analyzed with chi-square tests, and questions with numerically coded responses were analyzed with either T-tests or one-way analysis of variance (ANOVA> with Tukey's multiple comparison procedure. Complete results are available from Office of Institutional Planning and Research upon request. (back)
4. A 95 percent confidence interval denotes the range of values which contains the true population value in 95 out of 100 possible samples of the graduating senior population. Additionally, margins of error for individual questions are usually smaller than the given margin of error for the sample because the variance of proportions in each survey item is almost always less than the 50/50 figure used in calculating the confidence interval. Thus, the margin of error given is conservative. (back)
