Goals today
• Learn strategies related to data presentation
• Learn about resources for images
• Learn about ideas to consider while creating presentations
• Learn basic tips for good presentation design
Tip 1: use bullets as talking points
• Slides aren’t documents aka “slideuments”
• Slides shouldn’t be your teleprompter
Duarte, p. 7
The audience will either read your slides or listen to you. They will not do both. So, ask yourself this: is it more important that they listen, or more effective if they read?
Duarte, p. 7
To keep bullets brief
• No sentences
• Two lines per bullet (?)
• Four bullets per slide (?) • It’s OK to go on to the next slide!
• Think headlines
Duarte, p. 150; Kosslyn p.
Learning to Ride
• Put training wheels on the bike
• Raise the training wheels so you wobble
• Wear clothing and helmet to protect yourself
• Remove the training wheels and practice falling on the grass
• Enjoy riding your bike wherever you need to go

Rudolph in action
• A PowerPoint feature
• That’s actually helpful!
• Focuses attention
• On what and when

Use PowerPoint’s Animation feature, and Effect Options. Choose After Animation to Hide or Dim
Think critically about images
• Do they convey: • concrete ideas
• relevant moods
• metaphors
• What messages do they convey? • cultural
Designing with images
• One large, striking image
• Patterned backgrounds- consider the font
• Contrast & transparency scales
• Please: no cheez
Imagery: fonts as images
Fonts create different moods, and also evoke different feelings. Do you see what I mean?
How does this font make you feel?
How about this one?
Pie Chart: Concerns • Don’t use special effects
• Shadowing • 3-D • Color choices are not pleasing (non-complimentary)
• Don’t use to display more than 2 – 3 data points • We can’t discern relative areas well

Bar Chart is Better! • We’re still comparing parts to the whole • We see differences in length more accurately than
differences in area • Simple color scheme doesn’t detract • Percentage labels on the bars
Hues vs. spectrum Anthony Robinson shows how spectral colors make it much harder to tell the difference in volume of tweets (which is quantitative data) during the 2012 presidential elections:
In conclusion…
• Know your audience and its needs
• Maintain consistency; use inconsistency for emphasis
• Edit, edit, edit
