Doubly robust (DR) estimators that combine regression adjustments and inverse probability weighting (IPW) are widely used in causal inference with observational data because they are claimed to be consistent when either the outcome or the treatment selection model is correctly specified (Scharfstein et al., 1999). This property of "double…

Multiple imputation (MI) is a popular method for handling missing data. In education research, it can be challenging to use MI because the data often have a clustered structure that need to be accommodated during MI. Although much research has considered applications of MI in hierarchical data, little is known about its use in cross-classified…

Advice on case selection in small-"N" research emphasizes controlling for confounding variables to facilitate inferential tests of a cross-case pattern. Yet many researchers embrace the "mechanismic worldview" and aim to construct explanations. Explanations differ from inferences because one explains an outcome at the…

Meta-studies are often conducted on empirical findings obtained from overlapping samples. Sample overlap is common in research fields that strongly rely on aggregated observational data (eg, economics and finance), where the same set of data may be used in several studies. More generally, sample overlap tends to occur whenever multiple estimates…

To date, hundreds of researchers have employed the method of Qualitative Comparative Analysis (QCA) for the purpose of causal inference. In a recent series of simulation studies, however, several authors have questioned the correctness of QCA in this connection. Some prominent representatives of the method have replied in turn that simulations…

In this response to John Raven's "Diving in Where Angels Fear to Tread: Pre-Requisites to Evidence-Based Interventions," Stephen Gorard questions whether Raven's claims that researchers have created a serious threat to the entire earth, perhaps all of science, the process of education, and the field of psychology due to a lack of logic…

John Raven's article concerns the relationship between policy and evidence, what role that relationship plays in shaping the society in which we live, and what role researchers might play in shaping the relationship between policy and evidence. Although published in a "Psychology of Education Review", some of the examples draw beyond the…

Though community-based participatory research (CBPR) boasts a robust history, challenges to conducting such work ethically and equitably remain. Common difficulties, such as addressing power dynamics and navigating mutuality, are heightened when doing participatory research with young people, specifically youth participatory action research…

Research has oftentimes been carried out in Indigenous communities for the sole benefit of the western researcher. As a result, feelings of distrust toward researchers and research institutions have become prevalent among Indigenous peoples. However, this distrust can be resolved through the use of research approaches and methods that reflect…

During the COVID-19 pandemic, the race to find an effective vaccine or treatment saw an 'extraordinary number' of clinical trials being conducted. While there were some key success stories, not all trials produced results that informed patient care. There was a significant amount of waste in clinical research during the pandemic which is said to…

Purpose: The aim of this article is to address some aspects of a cross-cultural interview study conducted in a PhD research project. This is done by reflecting on and discussing the influence of language and culture on the research process, as experienced by the researcher. Design/methodology/approach: The experiences have been taken from an…

The higher education sector has been slow to respond to charges of institutional racism, which is reflected in what research is regarded as valid and what is funded. Further, many areas of student provision fall outside of the direct control of higher education institutions, for example, accommodation which may be operated by private landlords.…

This article provides a reflexive account of the authors' experiences of the ethical challenges in conducting a higher degree by research (HDR) supervision project prompted by the ethics review process in a major Australian university. The authors also raise epistemological questions about the specific focus of the study, given the interrelations…

For meta-analysis of studies that report outcomes as binomial proportions, the most popular measure of effect is the odds ratio (OR), usually analyzed as log(OR). Many meta-analyses use the risk ratio (RR) and its logarithm because of its simpler interpretation. Although log(OR) and log(RR) are both unbounded, use of log(RR) must ensure that…

Standard generic inverse variance methods for the combination of single proportions are based on transformed proportions using the logit, arcsine, and Freeman-Tukey double arcsine transformations. Generalized linear mixed models are another more elaborate approach. Irrespective of the approach, meta-analysis results are typically back-transformed…
