WPC300 QUIZ 6

Question 1

Which are useful principles for data visualization?

•   The use of a wide range of colors is critical to emphasize distinctions
•    Including as many grids as possible is vital for fully specifying the data to be represented
•   The graph suggests a possible true effect
•    It is important to include pointed arrows whenever possible to really draw attention to the eyes

Question 2

Visualization of spatial data are most illustrative when shown using

•   Line graphs
•    Maps
•    Bar graph
•    Bubble graphs

Question 3

Deleting the grid lines in a chart

•   Decreases the data-ink ratio
•   Increases the data-ink ratio
•    Decreases the lie-factor
•    Increases the lie-factor

Question 4

Which of the following statements is a reason not to use a table for data visualization?

•   The table has more precise numbers
•    Tables display more information in less space than a chart
•    Tables cannot easily show trends
•    Large amount of information can be included in a very small space

Question 5

Do a quick google search and find out about other data visualization tools. Which of the following is not a data visualization tool?

•   Weka
•    Qlik
•    Domo
•    Sisense

•   Cause of cholera outbreak
•   Interests of national debt during the war

•   Napoleon's invasion to Russia

Question 7

Which of the following basic data visualization principles violated for the graph shown below?

•   The chart should minimize graphical complexity
•   The chart should have a graphical integrity
•    The chart should tell a story
•    All three principles of data visualization violated.

Question 8

When the lie-factor of a graphical chart is more than 1,

•   The graph suggests a possible true effect
•   The graph simplifies the true effect
•   The size of the effect shown in the graph is bigger than the actual effect in the data.
•   The graph understates the true effect

Question 9

In confirmatory visualization

•   Users typically look for anomaly in the data
•    Users expect to see a certain pattern in the data
•    Users confirm the quality of data visualization
•    Users don't know what they are looking for

Question 10

Which of the following violates the principle of data visualization?

•   Avoid unnecessary chart junk
•   The lie-factor should be closely equal to 1
•   The data-ink ratio should be higher than 1
•   The chart should tell a story
