The Wilcoxon statistics are usually taught as nonparametric alternatives for the 1- and 2-sample Student-"t" statistics in situations where the data appear to arise from non-normal distributions, or where sample sizes are so small that we cannot check whether they do. In the past, critical values, based on exact tail areas, were…

In this study, eight statistical strategies were evaluated for selecting the parameterizations of loglinear models for smoothing the bivariate test score distributions used in nonequivalent groups with anchor test (NEAT) equating.

The primary objective of this article is to see if and how attendance policy influences class attendance in undergraduate-level principles of macroeconomics classes. The second objective, which is related to the first, is to examine whether the nature of the attendance policy matters in terms of its impact on class attendance behavior. The results…

It is common to consider Tukey's schematic ("full") boxplot as an informal test for the existence of outliers. While the procedure is useful, it should be used with caution, as at least 30% of samples from a normally-distributed population of any size will be flagged as containing an outlier, while for small samples (N less than 10) even extreme…

Rating scales have been used as a major assessment instrument to measure language performance on oral tasks. The present research concerned, under the same rating criteria, how far teachers interpreted students' speaking scores by using two different types of rating method, and how far students could benefit from the feedback of the description of…
