## Recommendations for revisions or improvements to existing OSF preregistration templates ## ---------- **About this wiki** This is a publicly editable wiki to add recommendations for improvements to existing OSF registration forms. The [Center for Open Science][1], which builds and maintains the OSF, occasionally updates the existing forms as needs arise and resources allow. You may add your suggestion to the list below. (See [here][2] for instructions on editing the wiki) Please contact COS, David Mellor, or Alex DeHaven with questions or comments: https://cos.io/about/team/ **Recommendations** - Add prompt for dealing with distributional assumptions. - In "[Dealing with Distributional Assumptions in Preregistered Research][3]," Williams and Albers recommend adding the following question to the standard OSF Prereg form: - What are the distributional assumptions of the statistical analyses you will be applying? - How have you accounted for the possibility of violations of these distributional assumptions? (Some options include selecting analysis methods that make assumptions that are as conservative as possible; preregistering robustness analyses which test the robustness of your findings to analysis strategies that make different assumptions; and/or pre-specifying a single primary analysis strategy, but noting that you will also report an exploratory investigation of the validity of distributional assumptions).
