IS498 mid term Questions with(A+)
Solutions
Give a brief summary of the example the book gives for the benefits of visualization
(contrast table vs. graph).-ANS - organized raw data, you can only answer/interpret a
basic understanding of trends.
graphs can highlight the full capabilities and findings of the data, which can be
enhanced with design elements such as color, interactivity, annotation(s), and
composition.
Mark-ANS - Points, lines or shapes that represent items of data
Attributes-ANS - Visual variations of marks to represent values associated with the
marks, properties such as size, color, position
Representing the online sales channel data from Chapter one in a visual chart IS
BETTER than representing it in a table. (t/f)-ANS - T
What is visual presentation in Kirk's terms (Chapter 1) and what are elements of it?-ANS
- making decisions about how to portray the data visually so that the subject
understanding it offers can be made accessible to the audience. Basically it is the charts
and which one shows the correct element of the data that you are trying to explain/most
relevant to the data.
What is data visualization in Kirk's terms?-ANS - Visual representation and presentation
of data to facilitate understanding.
data-ANS - names and amounts. It is groupings, descriptions and measurements. It is
dates and locations
visual representation-ANS - making decisions about how you are going to portray your
data visually so subject understanding made accessible to your audience.
presentation-ANS - design choices such as the possible application of interactivity,
features of annotation, all matters around colour usage, and the composition of the work
how representation and presentation connected example-ANS - The selection of a chart
, type inherently triggers a need to think about the space and place it will occupy on your
screen or page
understanding (data vis definition)-ANS - perceiving, interpreting and comprehending
perceiving-ANS - what do I see?
What chart is being used? What items of data do the marks represent? What value
associations do the attributes represent? What range of values are displayed? Are the
data and its representation trustworthy?
Interpreting-ANS - What does what you have seen mean, given the subject?
What features - shapes, patterns, differences or connections - are interesting? What
features are expected or unexpected? What features are important given the subject?
comprehending-ANS - The viewers now consider what the interpretations mean to
themselves
What has been learnt? Has it reinforced or challenged existing knowledge? Has it been
enlightened with new knowledge? What feelings have been stirred? Has the experience
had an impact emotionally? What does one do with this understanding? Is it just
knowledge acquired or something to inspire action, such as making a decision or
motivating a change in behaviour?
facilitating-ANS - realistically the most a visualiser can do
There are times when the onus is on us, and other times when the onus is on the
viewer.
Infographics-ANS - traditionally created for print consumption
contain charts (visualisation elements) but may also include illustrations, photo-imagery,
diagrams and text
produced for static output
Information visualisation-ANS - work that is primarily concerned with visualising abstract
data structures such as trees or graphs (networks) as well as other qualitative data
(therefore focusing more on relationships rather than quantities)
Information design-ANS - presentation of information
