  9. Identifying Your Purpose What questions do you need to answer? • Who is your audience? • What questions do they have? • What action will be taken? Source: Rebecca Vichniac: KIPP Data Summit, June 2014

  10. Identifying Your Purpose: Who is your audience • Role: what decisions do they make? What questions do they need answered? • Work flow: in what context will it be used? What information is needed regularly? How much time do they have? • Comfort and skills: how sophisticated are they with using the data? Do they enjoy digging into the numbers? • Business and data expertise: How familiar are they with the metrics? Do they understand where the data comes from? Are they familiar with the organization and terminology? Source: Rebecca Vichniac: KIPP Data Summit, June 2014

  27. Enhancing Visualizations Use Complimentary Colors for Comparisons

  28. Enhancing Visualizations Identify Groups of Attributes Use fewer than 6 colors

  29. Enhancing Visualizations Highlight Metric Patterns Less saturation: small values More saturation: larger values
