In the current study, we compare propensity score (PS) matching methods for data with a cross-classified structure, where each individual is clustered within more than one group, but the groups are not hierarchically organized. Through a Monte Carlo simulation study, we compared sequential cluster matching (SCM), preferential within cluster…

Studies analyzing clustered data sets using both multilevel models (MLMs) and ordinary least squares (OLS) regression have generally concluded that resulting point estimates, but not the standard errors, are comparable with each other. However, the accuracy of the estimates of OLS models is important to consider, as several alternative techniques…

The purpose of this article is to develop a statistical model that best explains variability in the number of school days suspended. Number of school days suspended is a count variable that may be zero-inflated and overdispersed relative to a Poisson model. Four models were examined: Poisson, negative binomial, Poisson hurdle, and negative…

Effects of sex and birth order on interactions between mothers and their six-month-old infants (matched in social class, infant's birth order, and sex) were studied using different sequential behavioral analyses. Results for each method are discussed. (Author/AEF)

Study investigates the adequacy of predicting differential value systems of college students from their American College Test (ACT) scores. (Author)

This article has been written to point out why the analysis of covariance is a useful technique even when there is no difference between the groups being compared in terms of mean scores on the concomitant variable. (Author)

There is little definitive research to support coeducational grouping as the optimal grouping pattern for first grade boys and girls. (Authors)

Pupil control ideology is conceptualized in terms of a continuum ranging from custodialism at one extreme to humanism at the other extreme. (Authors/MB)
