Presentation of Data • PowerPoint conveys data at relatively low bandwidth
Tables, Charts, and Graphs • Avoid tables & figures from journals – they do not project well • Tables & figures should be clearly labeled, and make sense at a glance • Orient the audience & walk them through the data
Tables, Charts & Graphs • You’ve failed if you have to begin with an apology • Limit data to what is necessary to convey your point • But don’t deceive • Highlight key points
