A Critical Look at Presenting Science: Daniel Poppel

Daniel Poppel's talk is a tour de force of presenting science - equal parts wit, clarity, brevity, and humility.

A good example of presenting data can be seen at 9:12. On the top panel, he presents groups means with error bars and a best fit line. The x-axis is tone frequency in Hz, therefore assuming interval scaling is more likely to hold. On the bottom panel, he shows data for individual trials with error bars. Then he goes one step further by presenting individual participants' data with error bars. The audience can decide at which level the data should be averaged, if at all. Remember: not all data should be averaged.

Those three graphs provide the audience with the information needed to make their own informed decisions concerning the validity of his conclusions.
