Limited Usefulness of Capture Procedure and Capture Percentage for Evaluating Reproducibility in Psychological Science
2018
In psychological science, there is an increasing concern regarding the reproducibility of scientific findings. For instance, Replication Project: Psychology (Open Science Collaboration, 2015) found that the proportion of successful replication in psychology was 41%. This proportion was calculated based on Cumming and Maillardet’s (2006) widely employed capture procedure (CPro) and capture percentage (CPer). Despite the popularity of CPro and CPer, we believe that using them may lead to an incorrect conclusion of (a) successful replication when the population effect sizes in the original and replicated studies are different; and (b) unsuccessful replication when the population effect sizes i…
Premature conclusions about the signal‐to‐noise ratio in structural equation modeling research : A commentary on Yuan and Fang (2023)
2023
In a recent article published in this journal, Yuan and Fang (British Journal of Mathematical and Statistical Psychology, 2023) suggest comparing structural equation modeling (SEM), also known as covariance-based SEM (CB-SEM), estimated by normal-distribution-based maximum likelihood (NML), to regression analysis with (weighted) composites estimated by least squares (LS) in terms of their signal-to-noise ratio (SNR). They summarize their findings in the statement that “[c]ontrary to the common belief that CB-SEM is the preferred method for the analysis of observational data, this article shows that regression analysis via weighted composites yields parameter estimates with much smaller stan…
Creatividad Organizacional: un estudio cuantitativo de la eficacia de los programas de entrenamiento en creatividad
2016
Las organizaciones actuales necesitan desarrollar sus mejores capacidades para sobrevivir en entornos altamente dinámicos y exigentes, para ello la creatividad resulta esencial. Con el objetivo de potenciar la creatividad en las organizaciones se han desarrollado numerosos programas de entrenamiento, pero muy pocos se han sometido a un análisis científico que avale su eficacia. Los escasos datos existentes sobre la eficacia son, frecuentemente, contradictorios, lo que indica la necesidad de abordar un estudio de concreción de tales resultados. La presente investigación analiza y sintetiza los resultados obtenidos en 32 estudios primarios sobre la eficacia de los programas de entrenamiento d…
Utility of Alternative Effect Size Statistics and the Development of a Web-Based Calculator: Shiny-AESC
2018
Alternative displays of effect size statistics can enhance the understandability and impact of validity evidence in a variety of applied settings. Arguably, the proliferation of alternative effect size statistics has been limited due to the lack of user-friendly tools to create them. Common statistical packages do not readily produce these alternative effect sizes and existing tools are outdated and inaccessible. In this paper, I introduce a free-to-use web-based calculator (https://dczhang.shinyapps.io/expectancyApp/) for generating alternative effect size displays from empirical data. This calculator requires no mathematical or programming expertise, and therefore, is ideal for academics …
