This is the second in a series of guides to open research created for LSE researchers under the auspices of LSE's Open Research Working Group. This guide covers some basic steps you will need to take when creating and submitting a preregistration, pre-analysis plan or registered report, with options for various different methodologies. Preregistration and pre-analysis plans are ways to document your methods and analysis decisions ahead of time. A registered report adds a journal’s peer review process before data is collected (you’ll get feedback on your preregistration and can modify it before conducting the work you describe). Registering your methods ahead of time has different benefits for different methodologies.
