QuestionQ15

Operationalizing an Analytics Project and Data Visualization Techniques

Which visualization method should be avoided?

  • A Using a small number of contrasting colors to draw distinctions
  • B Using tables of numbers to present all of the data visually
  • C Achieving a high data-ink ratio
  • D Using visuals to illustrate key points
Explanation

Tables of numbers are appropriate when exact values must be looked up, but they should not be used to present all data as a visualization because they make comparisons, trends, and key patterns harder to perceive. Effective visuals use graphical encodings to communicate the important points.
