Week 1-Visuals Flashcards
3 components of structing your thinking ?
Think about the objective
What surprises you about the data
Are there any patterns you notice
Explain the McCandless Method
4 elements of creating visual graphs from data
What are the 4 elements of McCandless Method
Information
Story
Goal
Visual
Explain the story element of McCandless Method
what is the clear and compelling narrative of the data
Explain the information element of McCandless Method
what is the data you are working with
Explain the goal element of McCandless Method
A specific objective of the visual
Explain the Visual form of McCandless Method
effective use of visual expression, what’s the best visual for the project
What is the Kaisers Fung Check Up and what are the 3 questions
3 questions that determine if the visual is correct for the job
What is the practical question? (trying to accomplish)
What does the data say ?
what does the visual say ?
What are Marks and Channels
Marks are points, lines and shapes, etc.
Channels - controls appearance
Scatter Plot - Marks would be points, Channels would be size of points, color of points and horizontal position of points
What are 5 design principles
choose right visuals optimize the data use orientation efficiently color number of things
Explain the design principal choose the right visual ?
Do you want to use a simple or comprehensive graph
Explain the design principal optimize the data ?
Minimize boxes and unnecessary graphics
Explain the design principal use orientation efficiently?
Label and titles are clear
Explain the design principal color ?
Use consistent colors through the project
Explain the design principal number of things ?
Reduce number of plots or segments
Name 2 things you want to avoid when making a graph
cutting off the y-axis - this might make the gap between values look more than it really is
limiting your scoop - if you only show points that validate your objective it’s misleading
What would you generally use a bar graph for ?
For ranking categories
x-axis would be categories
y-axis scale of values
What would you generally use line graphs for ?
Tracking changes over a time period
x-axis - time
y-axis - value
What would you generally use pie chart for ?
How much percent categories take up
What would you generally use maps for ?
show data geographically
Define correlation
values that relationships show patterns
Define causation
The result of another action. “Lightening & Thunder”
3 types of correlation ?
Positive, Negative, None
When is a column graph good for ?
used to compare totals between multiple variables.
What is a heat map and when is it useful ?
A geographic map that uses a map to display data
When is a pie graph useful
when you are dealing with percentages
When is a scatter plot useful
When you want to show relationships between 2 variables
When would generally not use a bar graph ?
When you have two or more variables
When would you use a donut chart
when it might be a benefit to show a total in the middle
What are 3 area charts ?
Regular, Stacked, 100 %
