DATA VISUALIZATION EXPLORING AND
EXPLAINING WITH DATA CERTIFICATION
EVALUATION EXAMS SET FULL QUESTIONS
AND COMPLETE SOLUTION
●● Anscombe's Quartet
Answer: four datasets that have the same simple descriptive statistics
(mean, median, correlation, varian, linear regression line), yet appear
very different when graphed.
●● How do we Visualize? (Module 1)
Answer: - Module 1: Foundations
> Introduction & Motivation
> Visual Design & Critique
> Visual Perception, Cognition, & Color
> Intro to Data Projects for Exploratory DA
●● How do we Visualize? (Module 2)
Answer: - Module 2: Working on Graphical Forms
> Composition and Comparison among items
> Distributions, Correlations, Uncertainty, Sig
> Proportions, Relationships, and Causality
,> Composition and Comparison over time
●● How do we Visualize? (Module 3)
Answer: - Module 3: Connection with Cases and Scenarios
> Mapping Data and Social Networks
> Visualizing Text and High Dim Data
> Narrative, Persuasion, Pitfalls, and Ethics
> Innovation, Research, People, Apps
●● Visualization Excellence
Answer: - Consists of complex ideas communicated with clarity,
precision, and efficiency
- Is nearly always multivariate
●● Tufte's Principles
Answer: 1) Have graphical integrity
2) Mind the lie factor
> Numbers should be directly proportional to the numerical quantities
represented
3) Maximize data-ink ratio
> Closer to 1.0, the better the graph is
4) Avoid chart junk
, 5) A visual project is good if it communicates a lot with a lit (BIG
MINIMALIST)
> AKA graphical excellence
**Minimalism and efficiency
●● Cairo's Principles
Answer: 1) Truthful
> Present things concisely, simply, clearly, and elegantly
2) Functional
> Choose graphic forms to help people encode information correctly
3) Beautiful
> Attractive and pleasing things work better
> Balanced mix of sensual and intellectual pleasure
4) Insightful
> Good visualizations clear the path to making valuable discoveries that
would be inaccessible if the information were presented in a different
way
5) Enlightening
> Change people's minds for the better
> Choose topics ethically and wisely
●● Visual Critique by Berinato
Answer: - Make a note of the first things you see
