#1 Mistake in Science Talks: The Assumption That the Audience Knows What You are Talking About
Keep it Simple: Explain!
Introduction- Observation
Keep it simple: engage the audienceSets up the rationale for studyAbstract talks: the first slide reflects titleLong talks: Historical basis of problem Current understanding Background information
Must have one and be able to state it
•Make no assumptions •Be specific
Tailor description to audienceSimplifyExplain methodsExplain abbreviations and jargonTime line must be clear
Methods
In order to measure isoprostanes, we first collected pig urine
Figures and Data Slides Declarative title Point to axes-describe 1 min per slide Speak to the slide Don’t over-interpret data Avoid tables!
Common Errors in Data Display and Graphing
Indexing/ProportionalityScalingReadabilityComplexityCredibility
After careful study, most investigators have concluded that tables generally stink as a way to portray information to an audience.
Summary
Conclusion
If you want to present a good talk, avoid tables.
Proportionality Problems: What is a Doubling?

Summary: be concise statement of facts
Conclusions: meaning or lesson speculations
Problems and Plans: what is next what to fix
Oh, yes: finally
• you probably shouldn’t make every slide a different font and color
