Abstract Central to understanding human behavior is a comprehensive mapping of brain-behavior relations within the context lifespan development. Reproducible discoveries depend upon well-powered samples reliable data. We provide scientific community two, 10-minute, multi-echo functional MRI (ME-fMRI) runs, and structural (T1-MPRAGE), from 181 healthy younger (ages 18–34 y) 120 older adults 60–89 y). T2-FLAIR MRIs behavioral assessments are available in majority subset over 250 participants....
Results of simulation studies evaluating the performance statistical methods can have a major impact on way empirical research is implemented. However, so far there limited evidence replicability studies. Eight highly cited were selected, and their was assessed by teams replicators with formal training in quantitative methodology. The used information original publications to write code aim replicating results. primary outcome determine feasibility based reported supplementary materials....
Across subfields of psychology, researchers frequently encounter count variables (i.e., non-negative integer values, which result from counted measurements). Although are common in psychological research (e.g., frequency behaviours or symptoms), may not be aware appropriate statistical procedures for modelling and drawing inferences data. Specialised regression techniques generalised linear models zero-augmented models) have been developed the unique properties data, but they can seem...
Psychological research is rife with inappropriately concluding "no effect" between predictors and outcome in regression models following statistically nonsignificant results.However, this approach methodologically flawed because failing to reject the null hypothesis using traditional, difference-based tests does not mean true.Using leads high rates of incorrect conclusions that flood psychological literature.This paper introduces a novel, sound alternative.In paper, we demonstrate how an...

Reporting and interpreting effect sizes has been recommended by all major bodies within the field of Psychology. In this systematic review, we investigated reporting ES in six Social-Personality Psychology journals from 2018, given that area at center Psychology’s replication crisis. Our results highlight although is near perfect (even for follow-up tests), magnitude ESs, including confidence intervals precision needs development. We also widespread confusion regarding interpretations...

Linear models are particularly vulnerable to influential observations which disproportionately affect the model's parameter estimates.Multiple statistics and numerous cut-off values have been proposed detect highly including Cook's Distance (CD), Standardized Difference of Fits (DFFITS) Beta (DFBETAS).This paper reports on a Monte Carlo simulation study that assesses effectiveness these methods recommended under various conditions, different sample sizes, numbers predictors, strengths...

Bayesian statistics has gained substantial popularity in the social sciences, particularly psychology. Despite its growing prominence psychological literature, many researchers remain unacquainted with methods and their advantages. This tutorial addresses needs of curious applied psychology introduces analysis as an accessible powerful tool. We begin by comparing frequentist approaches, redefining fundamental terms from both perspectives practical illustrations. Our exploration includes...

Abstract The biggest difference in statistical training from previous decades is the increased use of software. However, little research examines how software impacts learning statistics. Assessing value to demands appropriate, valid, and reliable measures. present study expands arsenal tools by reporting on psychometric properties Value Software Statistical Learning (VSSL) scale an undergraduate student sample. We propose a brief measure with strong support assess students' perceived...
