Quiz 2: Visualization

Started: Sep

Question 1 1 pts

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

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

Question 2 1 pts

Which of the following statement(s) about charts is false?

• A chart should minimize graphical complexity
• A chart should have graphical integrity
• None of the other answers are false
• A chart should tell a story

Question 3 1 pts

In order for a chart to have graphical integrity, the lie factor must be:

• greater than 1
• less than 1
• close to zero
• close to 1

Question 4 1 pts

Deleting the grid lines in a chart

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

Question 5 1 pts

Which of the following violates the principle of data visualization?

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

Question 6 1 pts

In for a chart to minimize graphical complexity, the data-ink ratio must be:

• close to 1
• less than 1
• close to zero
• greater than 1

Question 7 1 pts

Which are useful principles for data visualization?

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

Question 8 1 pts

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

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

Question 9 1 pts

What best describes the nature of a rose diagram?

• Plots data using a circular historical plot
• Represents various species of flowers
• Rarely used for azimuthal data
• Uses various colors to represent cause of mortality

Question 10 1 pts

Which of the following statement(s) about charts is true?

• The more data ink, the better
• Data ink can sometimes help tell a richer story
• We should make as many grids as possible in a chart
• A useless chart is called "chart junk"
