Here we describe the contents of the OSF project “Psychological Science April 2019 Data Badge Investigation” (https://osf.io/xzke7/). Under "Phase 1 reports" we collected the reports of each reproducer about each article. These individual reports are unstructured, with some reproducers deciding to include further information such as code, and others focusing on the narrative report of their reproduction attempts. Based on the individual reports, the groups of reproducers for each article agreed on a summary report of their overall findings. These can be found in the folder "Phase 2 reports". The individual and group reproducibility ratings can be found in the folder “Ratings and Information about Articles”, in the file Reproducibility_Ratings.csv. In the same folder, Articles_Summary.xlsx includes further information about each article, tables.R provides the code used to generate Table 1 and 2 in the manuscript related to this project, and ratings-figures.R provides code for supplementary figures. “Email_to_Authors.pdf” is the template email used to contact the authors of the articles under investigation prior to preprinting of the manuscript connected to this OSF project.
