Before analysis comes the messy work of evaluating, cleaning, and transforming data. This hands on workshop will introduce a free power tool to get the job done: OpenRefine. We will install Refine, create a project, and get oriented to the many features for exploring and transforming tabular data.
After the workshop, please complete the assessment survey. This helps us make sure our workshops are always getting better.
