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

 

Question 6

Florence Nightingale's rose diagram tells a story about

  •   Cause of cholera outbreak

  •   Soldier's cause of mortality in the hospital during the work
  •   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
