This 6-day training will engage OSF policy fellows in a series of discussions on how to re-think evidence-based, forward-looking and data-enabled policy advocacy. The first segment will familiarize fellows with the most important methods for data collection, analysis and operationalisation of research questions. It will draw on quantitative and qualitative methodological approaches with an emphasis on how to present data in charts and tables and how to conduct and interpret more complex statistical analyses. The second segment introduces the fundamentals of research design with an emphasis on how to present data in charts and tables and how to conduct and interpret more complex statistical analyses. The final segment will then train fellows on how to structure analytical reports, papers and briefs and write effectively. It will also equip them with practical skills of effective advocacy planning for their policy paper, popularization of findings for decision makers, civil society, media and general population.
