###Getting to Know Data: ####General

  • Who published?
    • Just like the sources we interview have motivations, so too do data providers
    • Advocacy groups
    • Studies
    • Trade groups
  • When was it relevant?
  • Is the information current?
  • What does the data encompass?
  • How was it compiled?
  • Ask about the methodology and how calculations were made
    • If receiving from a database, ask for a record layout or schema
    • Ask someone to walk you through the findings
  • What does it tell you?
  • What doesn't it tell you?
    • Spot check everything.
    • Check for weird or conflicting values.
    • Incorrect percentages and calculations.
    • Multiple spellings of people, places and things.
    • How can it be benchmarked against other data sets?

###Diagnosing Data for Representation: ####Stats/Math

  • How are numbers contextualized in the representation?
  • How is the reference point for visual read introduced (baseline of 0 on charts? visual order of the image to suggest legibility)
  • How is math done in the viz? (are they explicit about % vs. abolute values and how faithfully the #s represent their images)
  • How are outliers, anomalies, awk data points explained/handled?

####Design

  • How many font styles/types are used?
  • How is color used? To convey data or for decor? Where could it be simplified? Do that.

####UX

  • Is the representation of data an effortless read?
  • How are graphs and numbers incremented, what is the baseline/reference point for charts?
