The data we encounter in real life often contain missing values. In sampling methods, missing value imputation is done with different methods. This article proposes novel logarithmic type imputation methods for estimating the population mean in the presence of missing data under ranked set sampling (RSS). According to the determined theoretical…

Generally, psychology (as well as school psychology) aligns with medicine in establishing and utilizing evidence-based practices (EBP). More recently, strong calls have been made and advanced to ensure that psychology evolves and incorporates social justice principles to safeguard equity, diversity, and inclusion to benefit all. This essay…

In this article, the authors address some of the scientific challenges associated with using observation as a research method. The authors ask how researchers contextualise and understand observation in terms of its theoretical underpinnings and how it is conducted. Using a vignette in the kindergarten context, the authors explore how observation…

In the early months of the COVID-19 pandemic, many research funding organizations were faced with the choice of suspending their peer review panels, or else continuing their decision-making processes virtually. Although seen part of a longer drive to make peer review more cost and time efficient as well as to combat climate and sustainability…

The paper has three major objectives. The first objective of the paper is to synthesize and define common categories of meta-analysis. The second objective is to propose a way to comprehend these common categories of meta-analysis through learning from their respective generic conceptual frameworks. The third objective is to point out which R…

Estimating confidence intervals (CIs) for the correlation has been a challenge because the correlation sampling distribution changes depending on the correlation magnitude. The Fisher z-transformation was one of the first attempts at estimating correlation CIs but has historically shown to not have acceptable coverage probability if data were…

In this article, we reflect on our experiences with teaching ethnographic skills and sensibilities to MSc students at a Dutch university. Using methods such as (self)observation, journaling and reflection, we highlight dilemmas (conceptual, practical, ethical) faced by students when doing ethnographic fieldwork and dilemmas that emerged in…

The variance-stabilizing Freeman-Tukey double arcsine transform was originally proposed for inference on single proportions. Subsequently, its use has been suggested in the context of meta-analysis of proportions. While some erratic behavior has been observed previously, here we point out and illustrate general issues of monotonicity and…

Introduction: Missing data are bound to occur in education intervention research. Reasons vary but always have the consequence of reducing sample sizes and can, under certain conditions, seriously bias estimated intervention effects. A wide array of methods have been developed for handling missing data (Enders, 2023). Whereas older approaches…

This study critically examines the biases and methodological shortcomings in studies comparing deaf and hearing populations, demonstrating their implications for both the reliability and ethics of research in deaf education. Upon reviewing the 20 most-cited deaf-hearing comparison studies, we identified recurring fallacies such as the presumption…

Social network research often depends on the willingness of respondents to provide personal information about themselves and alters. Survey design strategies that increase willingness to share this information are necessary for social network research to be feasible, especially when name generators are used for sampling because rosters are…

Valid consent requires the potential research participant understands the information provided. We examined current practice in 50 proposed Clinical Trials of Investigational Medicinal Products to determine how this understanding is checked. The majority of the proposals (n = 44) indicated confirmation of understanding would take place during an…

Purpose: This paper engages Olaf Zawacki-Richter and Insung Jung in a frank and penetrating conversation that seeks to ground, frame, and problematise research in the field conceptualised as "open, distance and digital education" (ODDE). Taking as starting point the recent publication of the landmark "Handbook of Open, Distance, and…

Introduction: The What Works Clearinghouse (WWC) reviews rigorous research on educational interventions with a goal of identifying "what works" and making that information accessible to educators and policymakers. In rating the quality of causal research, the WWC has historically prioritized internal validity over external validity. One…

The aim of this article is to call for qualitative researchers in education and other human sciences to grapple with recent developments in trauma studies and engage in reconceptualizing their research practices so that they pay attention to the catastrophic effects of colonialism on individuals and communities. Joining other critics who have…
