On the 2009 AP[c] Statistics Exam, students were asked to create a statistic to measure skewness in a distribution. This paper explores several of the most popular student responses and evaluates which statistic performs best when sampling from various skewed populations. (Contains 8 figures, 3 tables, and 4 footnotes.)

In late October 1967, the USS Scorpion was lost at sea, somewhere between the Azores and Norfolk Virginia. Dr. Craven of the U.S. Navy's Special Projects Division is credited with using Bayesian Search Theory to locate the submarine. Bayesian Search Theory is a straightforward and interesting application of Bayes' theorem which involves searching…

Intuitive predictions and judgments under conditions of uncertainty are often mediated by judgment heuristics that sometimes lead to biases. Using the classical conjunction bias example, the present study examines the relationship between receptivity to metacognitive executive training and emotion-based learning ability indexed by Iowa Gambling…

Along with physician education in depression recognition and treatment, restricting lethal methods is an effective suicide prevention strategy. The present study surveyed a random sample (N = 697) of Ohio licensed social workers regarding client firearm assessment and safety counseling. Analyses sought to determine what independent factors would…

In spontaneous speech, speakers sometimes replace a word they have just produced or started producing by another word. The present study reports that in these replacement repairs, low-frequency replaced words are more likely to be interrupted prior to completion than high-frequency words, providing support to the hypothesis that the production of…

States and school districts are searching for strategies to raise the college and career readiness of high school graduates--imperative in an era when postsecondary credentials are the key to good jobs, better pay, and stronger economies. The creation and implementation of higher graduation standards aligned to college and career expectations is…

Overskilling is the phenomenon whereby a worker's skills are underutilised in his or her job. Overskilled workers are employed, but they are underutilised and mismatched, in that their skills and abilities are not a good match with the requirements of the job.

There is extensive research pointing to the positive effects of education in the form of labour market outcomes. These outcomes are vital when evaluating education; there are however additional outcomes of education that might also be important for quality of life. From this point of view, education could affect non-market areas such as democracy,…

Several German states recently introduced tuition fees for university education. We investigate whether these tuition fees influence the mobility of university applicants. Based on administrative data of applicants for medical schools in Germany, we estimate the effect of tuition fees on the probability of applying for a university in the home…

This causal-comparative study evaluated a 30-week chess instructional program implemented within special education math classes for students in the sixth, seventh, and eighth grades in a suburban middle school located in the southwestern United States. An analysis of covariance (ANCOVA) was utilized to compare the adjusted means for the comparison…

This study focuses on elementary teachers' comprehension of flooding before and after inquiry-based professional development (PD). There was an improvement in teachers' understanding toward a normative view from pre- to post-test (n = 17, mean gain = 4.3, SD = 3.27). Several misunderstandings and a general lack of knowledge about flooding emerged…

Propensity score methods allow investigators to estimate causal treatment effects using observational or nonrandomized data. In this article we provide a practical illustration of the appropriate steps in conducting propensity score analyses. For illustrative purposes, we use a sample of current smokers who were discharged alive after being…
