This document discusses incorporating numeric and statistical data sources into library instruction. It begins by introducing John Snow's cholera map as an example data source and asks librarians about data sources they have used. It then defines statistical literacy and notes how data is referenced in ACRL standards. Sample student learning outcomes and activities involving USA Today snapshots and Pew Research Center topics are presented. Additional resources on data and statistical literacy for librarians are provided. The goal is to encourage librarians not to fear using data sources in their teaching and provide ideas for doing so.
