Question 1

2 / 2 pts

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

2 / 2 pts

Visualization of spatial data are most illustrative when shown using

•   Line graphs
•   Maps
•   Bar graph
•   Bubble graphs

 Question 3

2 / 2 pts

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

2 / 2 pts

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

2 / 2 pts

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

Question 6

2 / 2 pts

Florence Nightingale's rose diagram tells a story about

•   Cause of cholera outbreak
•   Interests of national debt during the war
•   Soldier's cause of mortality in the hospital during the work
•   Napoleon's invasion to Russia

Question 7

2 / 2 pts

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.

 Keep the axis same to maintain graphical integrity.

 Question 8

2 / 2 pts

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

2 / 2 pts

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

2 / 2 pts

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
