Data Visualization - answer The process of presenting data and
conveying information in a visually appealing manner using:
- Tables
- Charts/graphs
- Maps
- Dashboards
benefits of data visualization - answer • Identify data errors and
outliers.
• Highlight important relationships and patterns in
the data.
• Make sense and interpret output from data analyses.
Data visualization evaluation - answer data-ink ratio
general design principles
design options
data-ink ratio - answer The ratio of total amount of "ink" used to
convey the meaning of the data (i.e., useful information) to the total
amount of "ink" used in the visual (i.e., both useful and useless
information).
- What was annual sales?
, General Design Principles - answer • Avoid distractors (e.g.,
unnecessary use of color/lines).
• Increase readability (e.g., font size, "white space").
• Keep it simple.
when to use a table - answer values have very different magnitudes
values are measured using different units
precise comparisons must be made
focus is on specific numeric values
when to use a chart - answer focus is on relative numeric values
approximate comparisons suffice
values are measured using the same units
when values have very similar magnitudes
Data visualization is useful for _____. - answer detecting data errors
and outliers
evaluate effectiveness of a visual design - answer data-ink ratio
general design principles
Which of the following is a distractor that should be avoided in
visual design? - answer unnecessary use of colors
Values have very different magnitudes.
Values are measured using different units.
