1 Stage 1 Registered Report: The influence of journal submission guidelines on authors’ reporting of statistics and use of open research practices: five years later Ingrid Boedker*, David Giofrè*, Geoff Cumming § and Patrizio Tressoldi 1 ° *Department of Education, DISFOR, University of Genoa, Italy § School of Psychology and Public Health, La Trobe University, Australia °Studium Patavinum, University of Padua, Italy [version 9/4/2021] Abstract The changes in statistical practices and reporting have been documented by Giofrè et al. (2017), who investigated ten statistical and open practices in two high ranking journals (Psychological Science [PS] and Journal of Experimental Psychology, General [JEPG]): Null hypothesis significance testing; confidence or credible intervals; meta-analysis of the results of multiple experiments; confidence intervals interpretation; effect size interpretation; sample size determination; sample size stopping rule; data availability; materials availability; preregistered design and analysis plan. The investigation was based on an analysis of all papers published in these journals between 2013 and the 2015. The aim of the present study is to follow up changes in both PS and the JEPG in subsequent years, from 2016 to 2020 adding code availability as further open practice. Keywords: statistical practices; open science practices; authors submission guidelines. 1 Corresponding author: patrizio.tressoldi@unipd.it
