DSC119_Chap 3: Data Visualization Structure

The following tree diagram shows a seniority and descendant in a family tree.  How many branches does this tree diagram have?

• 16

• 17

• 18

• 19

Which of the following chart is the type of hierarchical-tree diagram?

• Sunburst chart

• Network graph

• Network Map

• Node-Link diagram

The following statements about the relational-network are true, EXCEPT:

• Network graph uses nodes and link lines to represent graphical depiction of the network.

• Relational-network demonstrates relationships between dataset with less words to visualise how things are interconnected.

• Relational-network is also called radial tree.

• Nodes and links can be resized based on an assigned value.

What is/are other visualisations that can be represented for trends, timelines, and flows?

• I

• I & II

• I, II & IV

• All of the above

A scaled timeline ________________.

• allows viewer to see patterns over any selected time periods or how events are distributed for one particular period.

• shows list of events randomly on the timeline.

• shows dataset ranges between a minimum and a maximum value.

• is also known as a span chart.

What is the best chart to visualise data in Table 1?

• Tree Diagram

• Sunburst chart

• Treemap Diagram

• Radial Tree

Which illustration best depicts the sequence of events?

• Radial tree

• Timeline

• Gantt chart

• Bar chart

This type of chart is a variation of the tree map.  A circle is used to symbolize each node of the tree, and circles are used to represent each of its child nodes. Each circle's size can relate to a particular value, giving more insight to the plot.

The statement above is referred to as __________.

• Circular packing chart

• Sunburst chart

• Radial Chart

• Circle Proportional Area Chart

Figure 2 presents a four-sunburst chart of students' learning behavior and learning outcome. Is the following statement describe about the chart correctly?  

"Modules 3 and 4 are significantly harder than modules 1 and 2, judging by both the fraction of students in InitP and the total fraction of students who passed the module either before or after accessing the IC . The total number of passing students is the sum of the InitP group and the Eff group"

• Yes it is correct

• No it is wrong

• It is partly correct

• It is not related at all

_________ is a type of ________  chart, used to display parts of a whole and change over time.

• Stacked column chart, comparison

• Scatter chart, distribution

• Scatter chart, relationship

• Pie chart, composition
