Training Modules

NIH developed four video modules with accompanying discussion materials that focus on integral components of reproducibility and rigor in the research endeavor, such as bias, blinding, and exclusion criteria. These are not comprehensive training modules. They may serve as a foundation upon which to build further education, training, and discussion.

These modules can also be found on the NIGMS Clearinghouse for Training Modules to Enhance Data Reproducibility site, along with other training videos.
