CSE 578 Data Visualization UPDATED
Exam Questions and CORRECT Answers
Data processing - CORRECT ANSWER -user knows what he/she wants and has a
function to compute it
Querying - CORRECT ANSWER -user knows what he or she wants and can describe it
Navigation - CORRECT ANSWER -user knows what he or she wants and use cannot
describe it or locate it
Exploration - CORRECT ANSWER -user doesn't know what he or she wants. Wants to
acquire new knowledge and reveal new facts
5 Types of Exploration Tools - CORRECT ANSWER -1. Analysis (identify common
patterns or outliers)
2. Comparison (quantify similarities/differences)
3. Aggregation (create groups and clusters)
4. Transformation (use a more convenient representation)
5. Visualization
3Vs - CORRECT ANSWER -Volume, velocity, variety
HMLE - CORRECT ANSWER -High dimensional (lots of different things we want to
explore)
Multi modal (different ways needed to visualize it)
Inter-linked (data is linked, sometimes null, sometimes implicit)
, Evolving (underlying patterns change)
INS - CORRECT ANSWER -Imprecision
Noise
Sparsity
Cognition - CORRECT ANSWER -The mental action of efficiently and effectively being
able to process information into thoughts, knowledge, and insights
Visualization - CORRECT ANSWER -Graphically representing data to assist the
processing of information into knowledge, insights, and thoughts.
Uses exploratory data analysis to find trends and patterns in datasets.
Main components of a sequence - CORRECT ANSWER -starting point, ending point,
length
