Although the use of real-world data sets is encouraged when teaching statistics, it can be difficult for instructors to find meaningful data for introducing students to univariate descriptive statistics such as the mean, median, and percentiles. The recent lead contamination of the water supply in Flint, Michigan, provides a real-life data set…

Recently, studies have adopted fixed effects modeling to identify the returns to college. This method has the advantage over ordinary least squares estimates in that unobservable, individual-level characteristics that may bias the estimated returns are differenced out. But the method requires extensive longitudinal data and involves complex…

Many universities integrate leadership as a core component of agricultural education. Interestingly, little research has been conducted on the impact of leadership courses comparing the perceived leadership skills and abilities of students with and without prior leadership experience. Socio-psychological measures of flow or optimal experience…

The rise of social media websites (e.g., Facebook) and online services such as Google AdWords and Amazon Mechanical Turk (MTurk) offers new opportunities for researchers to recruit study participants. Although researchers have started to use these emerging methods, little is known about how they perform in terms of cost efficiency and, more…

Rationale: Asthma is a variable condition with an apparent tendency for a natural decline in asthma symptoms and health care use occurring as children age. As a result, asthma interventions using a pre-post design may overestimate the intervention effect when no proper control group is available. Objectives: Investigate patterns of natural decline…

Purpose: The authors set out to determine (a) whether African American children's spontaneous spoken language met use criteria for a revised minimal competence core with original and added morphosyntactic patterns at different geographical locations, and (b) whether pass/fail status on this core was differentiated on other criterion measures of…

Background/Context: The increasing number of districts implementing mentoring and induction programs suggests that policymakers are aware of the need to increase the support available to new teachers. The argument underlying many of these programs is based, at least partly, on assumptions about beginning teachers' emotional responses to their…

Background: The purpose of this study was to describe provider activities in a convenience sample of School-Based Health Centers (SBHCs). The goal was to determine the relative proportion of time that clinic staff engaged in various patient care and non-patient care activities. Methods: All provider staff at 4 urban SBHCs participated in this…

This report is intended to provide a snapshot of public school services provided to kindergarten through twelfth (k-12) grade students with Autism Spectrum Disorder (ASD) across the state of Michigan (MI). The authors used a systematic sampling process to collect information from over 200 school professionals statewide, resulting in a high degree…

This study investigated the main effects of social support measures and their stress-buffering effects in two samples of homeless adults (Ns =249 and 219) obtained in the same large county (surrounding Detroit) at different points in time over an 8-year period (1992-1994 and 2000-2002). The findings suggest that the construct of social support,…

In assessing educational equity among school districts, according to the authors, researchers should control for differences across districts in the prices of educational inputs. This paper tests a suggested index for one educational input, teacher salaries. The suggested teacher-salary index, based on a supply-and-demand model using 12 demand and…

Background/Context: In order to develop effective strategies for retaining able and committed teachers, it is important to understand how new teachers experience their work with their colleagues. A previous qualitative study conducted by the authors and others presented a conceptual framework for understanding new teachers' experiences of the…
