The PDFs were created by a different mentor during the summer session, so I don’t have access to change sharing privileges for the links in the PDFs (and the one you included). However, if you view the STEM-Away forum posts, like the one [here]R Data Visualization. Host: Yves Gaetan, Resident R Expert at STEM-Away), the PDFs that require data files will have a link to an accessible file in the post, not the PDF (the link will be preceded by the word ‘Data’). Try the links below and let me know if the files are inaccesible:
As for the self-assessments and completion status of a module - for right now, these are self-regulated. Self-assessments should be completed when you feel as though you understand the material in that module and (for Modules 2-4) have successfully completed all the steps listed under Instructions. (Modules 2-4 build off each other, whereas modules 1, 6, and 7 are more conceptual.) We are working to implement benchmarking for each module so there is a definitive"end-point assessment", but for now it’s an independent process.
I hope this answers your questions and please let me know if there’s anything else I can help with!
