This article is devoted to the study of the possibilities of using methods of demographic analysis in order to do research on the educational mobility of college students, on the basis of administrative statistics. The standards that are demanded of present-day scientific analysis determine the necessity of bringing data of a new type into play,…

Medical students encountering patients with unfamiliar, unconventional sexual practices may have attitudes that can affect open communication during sexual history-taking. We measured changes in first-year US medical student attitudes toward 22 non-traditional sexual behaviors before and after exposure to human sexuality instruction. An…

Until recently, much of the research on students' understanding of statistical ideas has focused on their conceptions of center or on what constitutes a good sample. In the past decade research on students' statistical thinking has broadened and increasing interest has been paid to how students think about variability in data or variability in…

Compared to traditional classification methods, developing a peer group using the National Center for Educational Statistics (NCES) Integrated Postsecondary Education Data Systems (IPEDS) data allows institutions to add comparative dimensions, to update the peer group, and to track changes at peer institutions over time. Peer selection and…

In this paper, we propose a new prediction analysis model which combines the first order one variable Grey differential equation Model (abbreviated as GM(1,1) model) from grey system theory and time series Autoregressive Integrated Moving Average (ARIMA) model from statistics theory. We abbreviate the combined GM(1,1) ARIMA model as ARGM(1,1)…

A 1-year panel study of 591 children in fifth grade explored the accumulative effects of the presence and contexts of video game violence on aggression and the antiviolence norm in Japan, on the basis of a comprehensive content analysis of video game violence. The results suggest that contextual effects of violent video games are quite complex,…

A classroom exercise for undergraduate and beginning graduate students that takes about one class period is proposed and discussed. It is an easy, interesting exercise that demonstrates important aspects of sampling techniques (sample amount, particle size, and the representativeness of the sample in relation to the bulk material). The exercise…

In the summer of 2006, several major news outlets gave prominent coverage to a sociological study with a grim message: Americans' social isolation had increased radically since the 1980s. Whereas in 1985, Americans reported that, on average, they had 2.94 friends or family members with whom they discussed important matters, by 2004 that number had…

In 1970, prior to the 1972 enactment of Title IX, there were only 2.5 women's teams per school and a total of only about 16,000 female intercollegiate athletes. In 1977/1978, the academic year preceding the mandatory compliance date for Title IX, the number of varsity sports for women had grown to 5.61 per school. A decade later, in 1988, the…

Americans' perceptions of childhood disability have changed dramatically over the past century, as have their ideas about health and illness, medical developments, threats to children's health and development, and expectations for child functioning. Neal Halfon, Amy Houtrow, Kandyce Larson, and Paul Newacheck examine how these changes have…

How many students repeat a grade each year? How do retention rates vary across states and over time? Despite extensive research on the predictors and consequences of grade retention, there is no systematic way to quantify state-level retention rates; even national estimates rely on imperfect proxy measures. We present a conceptually simple…

This report provides the Nebraska Legislature with comparative statistics to monitor and evaluate progress toward achieving "three key priorities" for Nebraska's postsecondary education system: (1) Increase the number of students who enter postsecondary education in Nebraska; (2) Increase the percentage of students who enroll and…
